I made up a couple of ribbon blocks this weekend. Overall it is super easy, breaking it down into a 9 patch. The hardest part for me was getting the wing on the long pointy triangles to be perfect. I figured it out that it's the left wing of the tri-recs ruler set... which I don't own. So I made cardboard templates and have it working for me! I don't have any fancy quilting software to make out any graphs, so thank you, Iceblossom!
