Short answer: Quilting templates are best in 1/8 in. acrylic: thick enough to guide a rotary cutter safely and thin enough to read the fabric through. Engrave the seam allowance (usually 1/4 in.), grain line, and block name, and choose a frosted finish on one side so the template grips fabric instead of sliding.

Why make your own templates?

Store-bought rulers cover squares, triangles, and a few classic shapes. The moment you design your own block, scale a pattern up or down, or want an odd angle for a wedge or a curved drunkard's path piece, you're tracing onto cardboard or template plastic that wears out. A laser-cut acrylic template is exact, stays exact, and works with a rotary cutter for years.

Common custom pieces include hexagons and half-hexagons for English paper piecing, kite and diamond shapes for star blocks, clamshells and curves, wedge rulers for Dresden plates, applique shapes, and quilting design stencils for marking stitch lines.

What thickness to choose

  • 1/8 in. is the standard for rotary cutting templates. The blade rides along a solid wall and can't ride up onto the template the way it can with thin plastic.
  • 1/16 in. for tracing and marking templates and for quilting stencils you mark through. It's lighter and easier to see through, but don't use it with a rotary cutter.
  • 3/16 in. for large rulers over about 12 in. long, which can flex in 1/8 in.

Frosted or clear?

Clear sheet shows the fabric best, so you can center a motif for fussy cutting. The catch is that smooth acrylic slides on cotton. Frosted acrylic has a matte finish that grips better and hides scratches from the cutter, while you can still see the fabric through it when it's pressed flat. More on frosted acrylic. Many quilters also add small sandpaper or silicone dots to the back of either type for extra grip.

Lines and markings worth engraving

We engrave on the back of the template so the lines sit right against the fabric and you're not looking at them through the thickness, which avoids parallax. Useful markings:

  • The 1/4 in. seam allowance as a dashed line inside the cutting edge
  • Grain line arrows
  • Center lines and 1/8 in. or 1/4 in. grid lines
  • Block name, finished size, and "cut 4" style notes
  • Matching dots for setting in Y-seams

Engraved lines show white on clear or frosted sheet. See acrylic engraving for line widths and text sizes.

Design tips

  • Draw the cut size, not the finished size. Add the seam allowance to the outline yourself, or tell us and we'll do it. Mixing up the two is the most common mistake.
  • Radius the corners slightly, around 1/16 to 1/8 in., on outside corners that aren't seam points. Sharp acrylic points chip and snag fabric. Leave corners sharp only where you need an exact point to line up.
  • Blunt tips on triangles and diamonds (dog-ear trimming) help pieces line up when sewing.
  • Holes: a 1/8 in. hole at seam intersections lets you mark the dot with a pencil. A 1/4 in. hole near an edge lets you hang the template on a peg.
  • Size: laser tolerances are about ±0.005 in., so a set of hexagons will nest without gaps.

Tip: keep the template edge clean. A rotary blade that nicks into acrylic dulls quickly and leaves a groove that steers the next cut. Hold the blade upright against the edge rather than angled into it.

How to order

Send a drawing with the cutting outline and the engraved lines on separate layers through upload a drawing. If you're working from a printed pattern, describe the shape and size and we'll help draw it. Matching sets for a pattern, a guild, or a class can be ordered in quantity.

Questions

Can I use a rotary cutter against 1/8 in. acrylic?

Yes. 1/8 in. is the usual thickness for rotary cutting templates. Thinner 1/16 in. sheet is for tracing only, because the blade can ride over it.

How do I stop an acrylic template from slipping?

Choose frosted acrylic, which grips fabric better than clear, and add a few small grip dots on the back. Pressing down with your fingertips spread across the template helps more than pressing hard at one point.

Can you scale a pattern to a different block size?

Yes. Tell us the finished block size and seam allowance, and we'll scale the shape and redraw the seam line so it stays 1/4 in. instead of growing with the template.
