Outdoor DIY Projects: Stone Carving Techniques For Garden Enhancements

Stone carvings and sculptures are a stunning and classic complement to any outdoor design or landscaping project. Stone sculptures may create a focal point for your garden, a distinctive entrance for your company, or a way to draw attention to the natural beauty of a public area. They may also bring a sense of sophistication and elegance to any outdoor setting.

The longevity of stone sculptures is one of their primary advantages as landscaping elements. Stone is a naturally occurring material that weathers well, making it perfect for outdoor applications. Its beauty and integrity will endure over time, even when exposed to wind, rain, and extremely high or low temperatures.

You'll learn the fundamentals of carving stone to create artwork from this book. We'll go over how to select the best kind of rock and what equipment you should buy. We will also guide you through every step of the carving process, from planning your sculpture to polishing your finished stone work—and all the steps in between.


  • Select a 15–25 lb (6.8–11.3 kg) soft stone block, such as alabaster or soapstone. Steer clear of hard stones like marble and granite, which require specific tools to cut.
  • Work outside to prevent dust inhalation, and wear gloves, goggles, and a N95. To keep your stone steady while you cut, place it in a sandbag.
  • Use a chisel and hammer to chip away at the stone. After chiseling along the direction of the stone's grain, use a file to smooth out the sculpture's final shape.




If you're just starting out and don't have many carving tools, go for soapstone. Carving soapstone is quite simple. It may be formed with very little force and has the consistency of a dry bar of soap. If you are creating a little sculpture that is resistant to being scratched or pushed, use soapstone.

  • You can carve soapstone with your fingernails or with tough stones from your yard because it's sufficiently soft. It is available in various colors, including black, green, and gray.
  • Check out your neighborhood stone carving supplies store or get a soapstone block online.
  • There is asbestos in certain soapstones, which is harmful to breathe in. When working with soapstone, wear a N95 mask. 


If you want the ideal blend of strength and flexibility, purchase alabaster. The greatest material for robust, colorful sculpture is alabaster. It is available in a number of hues, including translucent, white, gray, beige, orange, yellow, and red. Alabaster can be purchased locally via art suppliers or online.

  • Alabaster still carves easily, despite being generally tougher than soapstone. This makes it ideal for novice sculptors since it doesn't require specialized equipment or a lot of work, and it maintains its shape.
  • Limestone is another option because it is easily carved and maintains its shape. But limestone is limited to tan and gray hues.

STEP 3: Steer clear of really hard stones like marble and granite

They are quite hard and challenging to carve. To carve them, you would need specific tools. They take a long time to carve and need a lot of effort.

  • Since granite and marble are most suited to sculptures and other large pieces that need to be durable, they are typically carved in large numbers.
  • Even skilled carvers could need up to eighty hours to complete a quite straightforward granite or marble sculpture.

STEP 4: Select a stone slab that is significantly bigger than the sculpture you have in mind

The process of carving is subtractive rather than additive. In contrast to painting a canvas, carving entails chiseling away stone fragments till the sculpture remains.

  • A 15–25 lb (6.8–11.3 kg) stone block is ideal for carving. Carving with a hammer and chisel on blocks weighing less than fifteen pounds will result in broken blocks, while larger blocks may require more time to complete sculptures.
  • To start, select a block weighing 15 lb (6.8 kg). Working with it will be simpler due to its lower size.

STEP 5: Check for fissures and cracks in your stone

Wet the stone with a spray bottle to make fractures and fissures more visible. There will probably be a few, but this is to be expected as stone is a naturally occurring substance.

  • Avoid utilizing a rock that has fractures running through the entire circumference of it. During the sculpting process, these kinds of flaws could cause the stone to shatter.
  • Use the back of a chisel or a hammer to tap large stone blocks in various places. If there is a "ringing" sound made by the block, it is likely that there are no concealed fractures in the stone. If it sounds like a "thud" without any rings, there might be big cracks under the surface.
  • Rather than a stone yard, get your stone from a seller of stone carvings. Try to choose a strong stone to work with by asking store staff or an expert carver for assistance.


STEP 1: When cutting, put on a full-face respirator or N95 mask

Stone may contain silica or asbestos, both of which are dangerous to breathe in. Use a full-face or N95 respirator that is asbestos-rated if at all possible. Even without these, a regular N95 mask will still provide more protection than none at all.

  • Before carving, wet the granite to help cut down on dust.
  • Operate outside, such as on a porch or yard.
  • Utilize a fan to remove dust while working.


As you carve the stone, tiny particles of material will fly off it. These could irritate or hurt your eyes if they get into them. Wear protective goggles whenever you chisel or sand your stone to avoid this.

  • Put the goggles over your prescription glasses if you wear them.
  • In case your current goggles scratch, always have an extra pair on hand.


As stone is designed with sharp and quality abrasive, it can lead to wounds, splinters, blisters, and scratches. When handling big stone blocks, put on work gloves. You can use gardening gloves for medium-sized or smaller bricks.

  • Sharp tool injuries can also be avoided with cut-resistant gloves.

STEP 4: Get a metal file, chisel, and a carving hammer

Pick a wide-faced, flat-faced, or double-sided carving hammer weighing between 1.5 and 2 lb (0.7 and 0.9 kg). Invest in a flat chisel with a straightforward, bi-sided tip. Invest in a set of three to four metal files designed for stone cutting, of varying diameters.

  • Look for a double-sided carving hammer at your neighborhood hardware store or purchase one online for $7–25.
  • You may get a stone chisel for $12–26 on Amazon or find one at a nearby hardware shop or seller of stone carving tools. To assist in fine-tuning your sculpture, you can also acquire a toothed chisel; they range in price from $15 to $30. Stone filing sets range in price from $8 to $20.

STEP 5: To support your stone block, purchase a sandbag

To lighten the weight, replace the sand in the sandbag with half of a kitty litter bag. To prevent cat litter from pouring out, tie the sandbag shut. As you work on it in later steps, you'll place your stone block on the sandbag.

  • For your sandbag, get bags of inexpensive, inferior cat litter. Because sand settles too fast and is heavy, it cannot sustain your stone block.
  • The bag shouldn't be filled more than halfway. Your sculpture will have room to rest on the additional area. 


STEP 1: Sketch your idea on a sheet of paper

Create an abstract shape for your first sculpture. Until you have more skill, steer clear of creating intricate sculptures like human statues. As you draw, visualize your composition. Despite being two-dimensional, your drawing will aid in your understanding of how your three-dimensional object needs to be molded.

  • To serve as a guide, you can also model your sculpture in clay. You can adjust the amount of clay until it takes on the shape you want.

STEP 2: Look at the stone to find the grain or bed direction

Stone has a "grain" called "bed" that resembles wood. Take note of the bed's orientation. In subsequent steps, make sure to shatter the stone anytime it is directed towards the bed. This makes the components appear more logically sized as opposed to haphazardly.

  • To make the bed lines easier to see, wet the stone. They will show up as recognisable patterns of color that flow in the same direction.

STEP 3: Make your design on the stone with a crayon

Make sure to leave your mark on the stone's sides. Verify that the drawings' height and breadth are accurate on all sides. This crayon drawing will serve as your guide when you carve your stone.

  • Don't write on your stone using pencils, pens, or markers. Pen and marker ink can leave permanent stains on stone, making pencil markings difficult to notice. 

STEP 4: With your dominant hand, hold the chisel and the hammer

Hold the chisel in the middle, just like you would a microphone. Make sure your chisel is always in contact with the stone by holding it firmly. Keep your chisel from bouncing or jiggling to prevent imprecise hits.

  • Place your thumb where your other fingers are on the side of the chisel. This lessens the chance that you could accidentally hit your thumb with the hammer.
  • Instead of using a toothed chisel while carving an edge, use a flat one. If you strike the rock with only a portion of your teeth on it, the teeth may break off, rendering your chisel unusable and posing a risk. 

STEP 5: Use your hammer to hit the chisel's end

Hold your chisel at a 45-degree angle or less with respect to the surface of the rock. Chips of stone will come off the rock as you continuously tap the chisel.

  • Do not hit the stone directly. A direct hit will result in a "stone bruise," which will render the stone white and leave a mark on your finished creation.
  • Use a shallow angle while striking the stone if your chisel gets embedded in it and does not chip away at the stone.
  • If you carve at an angle that is too shallow, your chisel will skip off the stone and leave nothing behind. Use a toothed chisel or strike at a deeper angle to correct this.

STEP 6: To keep it steady, place your stone on top of the sandbag

Your stone block will be easier to cut because you won't have to use as much energy to hold it stationary. Every few minutes, reposition the stone on the sandbag to maintain its centering.

  • If you can, carve while standing. This facilitates angling your chisel downward towards the ground, maximizing the force of each strike with your hammer and decreasing the movement of the stone.
  • Lean the stone against your body and push it against you if it continues to move on the sandbag. As you carve, make sure the surface is facing away from you.
  • If you're carving on a foldable table, cover one end of the legs with your stone and sandbag.

STEP 7: Instead of carving towards the edges of the stone, work towards the center

Because the stone is thinner and more brittle at the edges, this helps keep it from breaking. Face your chisel towards the center of the carving. When working with edges, strike perpendicular to the edge, but cut down its length.

  • If you carve towards the edges, you may inadvertently chip off too much stone.
  • Large chunks of stone will not fall off if you employ gradual, soft hammer strokes when carving towards the edge.

STEP 8: Cracks should be chiseled along rather than across

Instead of cutting at a straight angle, chisel in the direction of the fissures. File along fractures before applying the final touches to your stone to prevent flaking. This will also aid in disguise and smoothing over fractures.

  • Every stone slab has a few little cracks in it. Work with, not against, the fissures to minimize the quantity of lost stone.


STEP 1: To add the last details to your sculpture, use a file

Just keep your stone file away from you. Move the file away from you, raise it up, put it back where it was, and then push it once more. Repeat this process to smooth out chisel marks, add small details, and fine-tune the piece's final shape.

  • Straight steel files are best used on soft rocks like soapstone. Use riffler files for really intricate work.
  • The teeth on the majority of stone carving files are unidirectional, which means they can only cut in one direction.

STEP 2: Reattach any pieces that unintentionally came off with epoxy glue

If a significant stone fragment is lost in a larger sculpture, the design will be ruined. Use this technique. For instance, you may repair the arm section of a sculptural statue with epoxy glue.

  • Instead of just sticking stone fragments together, you might want to reconsider your plan for smaller sculptures. For instance, you may decide to etch an arrow rather than a heart.

STEP 3: Use paper with 220 grits to sand your sculpture

This will give your sculpture a more polished appearance by eliminating any last scratches and chisel marks. To prevent dust, moisten the stone and use wet/dry sandpaper; alternatively, sand the stone dry while wearing a mask or N95.

  • The quantity of grit grains per square inch is known as the grit number. The sanded product will be finer the higher the grit content.
  • Use abrasive belt or sandpaper of grit 80 or less only for rough stone surfaces, such as soapstone. Using coarse grits could harm your finished product.
  • You can see cracks and marks as you work when you sand dry; just be sure to wear a N95 mask or respirator.
