Besides D9P
What I did was I drew a line down the middle of 1/2 of my charm squares (if you cut, it would make rectangles). I then put 2 charm squares together. I sewed 1/4" on either side of the line. Cut. Now you have 2 sets of identical rectangles.
Rotate one 90 degrees. Draw line like before, sew on both sides like before, cut.
2 identical 4 patches. Repeat, put together, make pretty quilt.

Other pattern. Do the same thing but use the diagonal. Make 2 identical hour glass blocks. Much more point matching on this one :| I'm working on it now so no picture to post.
