How to make a multi-layer stencil from a photo

How does a multi-layer stencil work?

Instead of colours, it uses light and shade. The surface you paint on is the lightest tone. The first stencil opens where the picture is a little darker, the next where it is darker again, and the last only in the deepest shadows. Painted in that order, one over the other, the tones build a face or a scene. It is how spray-paint portraits and layered street art are made, and it works just as well with a brush or a sponge.

Which photo works best?

• Light from one side. A face lit from a window has clear highlights, mid tones and shadows. Flat, front-on flash light has none.
• Strong contrast. A photo that is all mid-grey splits into three similar greys.
• A plain background. Otherwise the background becomes part of every layer. Remove it first with the background remover if it is plain enough.

How many layers should you use?

Two paint layers give a bold, graphic look and are quick to cut. Three is the classic portrait. Four holds more detail, but it means more cutting, more painting and more chances for a sheet to go on slightly out of line. Start with three.

How do you make the stencils, step by step?

1. Drop the photo into the multi-layer stencil maker and choose the number of layers.
2. Set the design width. Smallest pieces and bridges are measured in millimetres at this size.
3. Raise Simplify until the shapes are bold enough to cut. Fine texture becomes tiny pieces that tear.
4. Check each sheet with the Sheet buttons. The layer list shows the order to paint, the suggested colour, and how many bridges each sheet has.
5. Download all the sheets as one SVG and cut each sheet from stencil film, card or vinyl.

Why stack the layers?

With stacking on, each sheet also opens over every darker area: the mid-tone sheet paints under the shadows as well. When the shadow sheet goes on a millimetre out of line, what peeks out is mid tone, not bare surface. It uses a little more paint and hides a lot of mistakes. Switch it off if you want each tone painted only where it shows.

How do you line the sheets up?

Every sheet has the same outline and four small cross-shaped holes in the corners, cut in exactly the same places. With the first sheet down, spray or dab lightly through the crosses so they mark the surface. When each later sheet goes down, line its crosses up over the painted ones, tape it, and paint. Let each layer dry before the next, or the stencil lifts wet paint.

Why do some pieces have little bridges?

An island is any part of a sheet that would be cut completely free: the middle of an eye, the centre of an O. Without a bridge it falls out when you lift the sheet and you lose that detail. The maker adds a thin bridge, a width you set in millimetres, from each island back to the sheet. It shows as a thin line in the painted result; most people touch it up with a brush.
