A good stencil comes from a good image, not just a good cutter. Photos are full of soft shading, and a stencil has no shading at all: every part of it is either cut away or left in place. Turning a photo into a stencil is mostly about deciding where that line falls, then making sure the pieces you leave behind stay attached.
This guide covers choosing an image, converting it to a cut-ready black-and-white outline, adding bridges so the middles of letters and shapes don't fall out, and cutting the stencil by hand or with a machine.
Quick comparison
Comparison of the products recommended in this guide
A precision craft knife with a self-healing cutting mat, sold together; Listed for scrapbooking and stencil cutting, so check exactly what is in the set (blades, mat size)
Blades are very sharp, so use care and keep them away from children
Cutting the same stencil accurately and repeatably
A compact Cricut machine with starter materials and digital content, per the listing; Cuts up to 4.5 inches wide, so it suits small stencils rather than large ones
Disposable stencils for fabric, such as T-shirts and tote bags
Letter-size freezer paper sheets with a plastic coating on one side, listed as printable; The coated side is pressed onto fabric with a warm iron to hold the stencil down
Pick an image with strong contrast and a clear subject: a silhouette, a bold logo, a portrait with deep shadows, a simple animal. Busy backgrounds, soft focus and low light make a poor stencil, because there is no clean line between what is cut and what is left. If your photo is cluttered, crop to the subject first or use a version with a plain background.
Step 2: Convert it to black and white
Upload the image to Image to SVG and use the automatic cutoff or move the threshold until the preview looks like the stencil you want: black areas are what you'll cut away. Use edge smoothness and the speck filter to clean up rough edges and tiny dots you don't want to cut. If your design is large, use Panel Mode instead to split it into panels at real size.
For a design with several tones, you can make more than one stencil from the same image at different cutoff settings, then paint from the lightest layer to the darkest.
Step 3: Add bridges so the islands stay in place
A stencil is one sheet. Any piece that is completely surrounded by a cut, like the center of an O, A, B or 8, would fall out. A bridge is a small strip you leave uncut to hold the island to the rest of the sheet. Use bridges that are thick enough to stay in one piece, but narrow enough not to spoil the look. A few millimeters is typical on a small stencil, and wider on a large one.
You can add bridges by drawing thin shapes over the gaps in your cutting software, or by leaving small gaps while you cut by hand. Stencil-style fonts have the bridges built in, which makes lettering much easier.
Step 4: Cut the stencil
Download the SVG for a cutting machine or the DXF for laser and CNC software, and check the size after importing. Do a small test cut first. For a hand cut, print the design, tape it over your stencil material and cut carefully along the lines on a cutting mat.
Step 5: Test and paint
Try the stencil on a scrap piece before the real surface. Hold it flat, use very little paint, dab instead of brushing, and lift it off while the paint is still wet. If paint creeps under the edges, use less paint or add a light repositionable adhesive. For help choosing materials, see our stencil materials guide.
Frequently asked questions
What kind of photo makes the best stencil?
One with strong contrast and a clear subject, such as a silhouette, a bold logo or a portrait with deep shadows. Busy or low-light photos turn into messy stencils.
What is a stencil bridge?
A small uncut strip that holds an island, like the middle of an O, to the rest of the stencil so it doesn't fall out. Without bridges, those pieces drop away when you cut.
Can I make a multi-color stencil from one photo?
Yes. Make several stencils from the same image at different cutoff settings, then paint from the lightest layer to the darkest, lining each one up carefully.
What if my stencil is bigger than my material?
Split it into panels with Panel Mode. Each panel is its own file at real size, and our large stencil guide shows how to line them up.
