Eli S. ★★★★★

These tiny triangles hold their shape perfectly for fussy cutting, and the acrylic templates make it easy to trim my fabric to size. I'm already planning another project with them.

Robert ★★★★★

These tiny triangles cut perfectly and hold their shape through hours of stitching, which makes piecing those intricate points a breeze. I've already ordered more for my next scrap-busting project.

Ryan C. ★★★★★

I was worried the papers might warp with glue, but these 3/8" equilateral triangles hold their shape perfectly and the precision cuts make them a joy to baste around.
