GailG, each rectangle block finishes out at 6" x 10". I made this quilt 10 blocks across and 7 down, so it will be 60" wide and 70" long, twin or large throw size. I used 5 fabrics: about 4 yards or 60 WOF strips. Today I just pieced another one but it is smaller, 8 blocks across and 6 down for a finished size of 48" x 60", throw size. This one has 48 blocks and took about 40 WOF strips. You will find it a simple one to do!
