This is my favorite block so far. The stripes really add a lot of the block. And it was easy to put together too! I finally went out and bought a disappearing ink marker last night, and it was very helpful in putting this block together. I used it to make sure the triangles were centered before attaching them.
This block is freezer paper-paper pieced, and the fabric is Kaffe Fassett's Kaffe's Red Shirt Stripes. I LOVE this fabric. Although for a shirt, it may be a little much :p
