Back to some easier piecing! Used Freezer paper for accuracy on the first two. Don't really know why on the instructions I found on the internet that C-3 seemed to cause problems!
For that one I cut 2" strips out of my background and focus fabrics and sewed about 24" together. I then cut these joined strips into 2" sections for the 4-patch and the rectangles that join them. It was a simple matter to sew 2 of the rectangles into the center square, sew (2) 4-patch to each end of the other 2 rectangles and join these to the other two sides to complete the block. (Did have to block mine a little)
