The block is 14-1/2 x 14-1/2 inches. I started it yesterday in a class I took on how to paper piece. The four blocks with multiple fabrics are the ones that are paper pieced.
It's a precise quilting method that allows you to make patchwork blocks with exceptional accuracy. You will have precise, uniform results, even when you are doing complicated points and seams.
You actually sew the fabric to the paper pattern in a certain order. I ripped out a whole lot when I first started, but the last of the four that I made, I actually didn't rip once.
There are whole books full of paper pieced quilt patterns. I'll probably do more with the method but not right now.
