The Signal block is machine pieced with small scraps of left-over fabric. The blue fabric is probably my favorite of the bunch.
Each block will be 4" completed... the first 50 block instructions can be purchased from Sentimental Stitches but instructions for blocks 51 through 196 are free. Check them out HERE!
If you're sewing along I'd love to see your completed blocks in the Flickr Group! :)
