Qbee-
When I make a 4DP (disappearing 4 patch for the a 12" I start with 4 7 1/2" squares and sew them in the traditional 4 patch block. Then I measure from the center lines and cut 2" on both sides that gives you 9 pieces to move around. The block I did for you is a disappearing 4 patch.

A disappearing 9 patch (d9p) is when you make a traditional 9 patch then cut in in half top to bottom and side to side then arrange it into a 4 patch to finish it. When you cut it in half you create the squares with the saching on 2 sides in 1 step instead of piecing it togther.

You just have to remember to add 1/2" for every seam that will be sewn, before and after doing the second cutting. For a 12" D9P you might want to start out with 9 4 3/4" square-that's adding 1/4" to each 4 1/2" square, this should give you a 1/4" play once you finish cutting the 9 patch and resewing it into a new design.
