72 quilt blocks
This awesome collection of 72 quilt blocks was actually generated automatically using a computer program written by Mark Jason Dominus. From what I can tell from his webpage, he was inspired by a girlfriend who was into quilting; when they got married, she made a quilt from these blocks as a present on their wedding day. Like there’s not enough to do in the run-up to a wedding….
These blocks are all based on a half-square triangle (HST). There are a million and one tutorials online about how to make HSTs — check out the Intro to Half Square Triangles from Connecting Threads or HST Tutorial and Maths Formula from Blossom Heart Quilts. If you’re feeling particularly brave, you can try the Magic 8 Method on Craftsy.
