Stencils 101: What Every Stencil Needs (Stencil Series, Part 1)

A stencil looks simple: a sheet with holes in it. It isn't. Get the material, the design or the application wrong and the whole project fails.

I get a lot of orders for custom stencils at M2C1 Designs, so I'm starting a series to help other crafters. This is part one: the basics every stencil needs, the two kinds I make, and a real customer job start to finish.

Anatomy of a stencil: islands and bridges

Every stencil comes down to two parts.

  • Islands are the open cut-outs where paint or ink passes through to your surface.
  • Bridges are the solid tabs that hold the inner and outer parts of the stencil together so the design doesn't fall apart.

Think of the letter O. Cut it out with no bridges and the center drops right out. Add two small bridges and the center stays put, but now your painted O has two gaps in it. That trade-off is why the type of stencil matters.

Adhesive vs. mylar: the two I make

Adhesive stencils handle fine detail with no bridges but can only be used once. Mylar stencils are reusable but need bridges.

Adhesive (temporary) Mylar
Best for Fine, detailed designs Designs you'll use again
Bridges Not needed Required
Tiny pieces The adhesive holds them in place Each one needs a bridge
Reusable No, one and done Yes

If a design has lots of tiny floating pieces, it's an adhesive job. If you want to paint the same design over and over, it's mylar, and the design has to be built with bridges.

Behind the scenes: a detailed logo stencil for T-Bird Electric

This customer's logo has bold lettering, small "Commercial-Residential-Industrial" text and a roadrunner full of fine lines. There's no way to bridge all those tiny pieces, so this is an adhesive stencil.

The key trick: weed the big pieces first, apply the whole stencil, then weed the fine pieces on the surface. The adhesive holds the stencil and every tiny piece exactly where it belongs.

  1. Seal the surface. This is a wood board, so it gets sealed first to keep paint from bleeding into the grain.
  2. Weed the big pieces. I pull the large areas while the stencil is still on its backing and leave the fine detail alone.
  3. Add transfer tape. The whole stencil moves to the board in one piece.
  4. Apply it with the hinge method (below). Press it down well, especially the edges.
  5. Weed the fine pieces on the board. This is where most stencils fail. Take your time.
  6. Mask off, then dab on the paint. Cover the surface around the stencil with painter's tape or paper so paint doesn't land where it shouldn't. Then dab, don't brush, so paint doesn't push under the edges.
  7. Dry it. A heat gun speeds this up.
  8. Peel. Then pick out any tiny pieces left behind. The stencil is done after one use.

The hinge method

The hinge method gets a stencil onto the surface exactly where you want it, with no shifting and fewer bubbles. Adhesive grabs the second it touches, so you only get one shot.

  1. Position it. Lay the stencil, transfer tape and backing still on, exactly where it goes.
  2. Make the hinge. Run a strip of painter's tape across the middle of the stencil.
  3. Peel one half. Flip one half up over the hinge, peel the backing off that half and cut the loose backing away.
  4. Lay it down. Smooth that half down, working from the hinge outward.
  5. Do the other half. Remove the hinge tape, flip the other half up, peel the backing and smooth outward.
  6. Lift the transfer tape. Smooth the whole stencil once more, then peel the transfer tape back at a sharp angle.

Small stencil? Put the hinge along the top edge instead and peel all the backing at once.

Why stencils fail

Most stencil fails come down to four things.

What goes wrong Why The fix
Paint bleeds into wood The surface wasn't sealed Seal the wood first
Centers fall out A reusable stencil was cut without bridges Build bridges into mylar designs
Fuzzy edges The stencil wasn't pressed down, so paint crept under Press it down well, especially the edges
It won't stick a second time Adhesive stencils are single use Use mylar for repeat jobs

Types of stencils

Beyond the material, stencils are sorted by how they're built, how they're applied and what they're for.

Type What it is
Layering A set of 3 to 6 stencils used in steps to build multi-color, shaded designs
Letter and alphabet Pre-cut letters, numbers and symbols for signs, labels and personalized projects
Background and pattern All-over repeating patterns for covering large areas of paper, walls or canvas
Masking and negative Shapes that block off an area so you paint around the edges instead of through the center
Adhesive / self-stick Low-tack vinyl or mesh-backed stencils that stop bleeding, even on uneven or curved surfaces
Border and edge Narrow repeating strips to frame pages, furniture edges or walls
Airbrush and face/body Thin, flexible stencils for makeup artistry and temporary body art
Tile and surface Large designs for floors, stair risers, backsplashes and patio concrete

What stencils are used for

If it has a surface, someone has stenciled it.

  • Walls and home decor: repeating patterns, borders, faux wallpaper and accent murals on walls and ceilings.
  • Furniture upcycling: details, numbers and geometric designs on dressers, tables, pots and wooden crates.
  • Signs and lettering: addresses, business logos, warning labels and seasonal wood and metal signs.
  • Paper crafts and scrapbooking: ink blending, embossing paste, chalk and sprays for cards, journals and layouts.
  • Fabric and apparel: t-shirts, canvas bags, pillows and quilting projects.
  • Street art: multi-layer spray-paint stencils for portraits and icons.
  • Mixed media and fine art: layered textures, modeling paste and background patterns on canvas.

Tips and tricks

Small habits make the difference between crisp lines and a fail.

  1. Weed big, then small. Fine pieces wait until the stencil is on the surface.
  2. Seal wood first. It keeps paint from bleeding into the grain.
  3. Seal the stencil edges. A thin coat of clear sealer or your base color over the stencil means any bleed blends in.
  4. Less paint is more. Blot your sponge on a paper towel first. Too much paint seeps under.
  5. Dab, don't brush. Brushing pushes paint under the edges.
  6. Test on scrap. Try your paint and surface before the real piece.
  7. Use a weeding hook. It lifts tiny pieces without tearing the stencil.
  8. Care for mylar. Clean it right after use and store it flat so it lasts.

My favorite: engraving with Citristrip

There are so many possibilities with adhesive stencils. My favorite is engraving with Citristrip, a method I discovered.
