Piece the strips into blocks that will measure 6-1/2" x 6-1/2" (unfinished) as shown in figure 7. Press all the seams in one direction. (The nice thing about this block is that you do not have to worry about matching seams!)
You will have 36 blocks measuring 6-1/2" x 6-1/2"
When you have completed all of Part Four, you can go to Part Five, the final part of our mystery quilt.
