4" x 7" Isosceles Triangles

The 4" x 7" size is perfect for larger blocks, and the paper holds its shape through multiple passes without tearing. I grabbed the seam allowance option and it’s been cutting my prep time way down—absolutely worth it for staying precise.

The acrylic windowed versions make it so easy to see exactly where my fabric lands before I stitch—no more guessing. I’ve already used these for half a dozen blocks and they hold their shape perfectly through all the handling.

I was a bit nervous about cutting my own papers, but these pre-cut triangles saved me so much time. The acrylic templates are rigid enough to hold shape while basting the seam allowance.
