I kept reading about a D9P and didn't have a clue what that meant so I Googled it and found a wonderful tutorial by Patsy (or Patty) Thompson on how to make the Disappearing 9 Patch. I love it! It may not be my next quilt, but it will definitely be in the next 2 or 3. I have been making crib size quilts when I want to try a new pattern. Someday when all my grandkids start having babies I am going to be well supplied.
