The fourth lesson was taught by Dan Rouse of Piece and Press blog. He showed us how to slice curves and then sew them back together. We began with a stack of 4 fat quarters and sliced them 4 ways. Then we shuffled them and sewed them back together, restacked them, and shuffled and sewed again. It makes some pretty blocks.
Here is my stack!
My block is on the bottom right side along with three others.
Finally, this is a quilt top Dan made on the first day while we were all sewing on our projects.
