Whereas the tube of the tube quilt from Missouri Star Co has 3 - 2 1/2" strips, this one has 2 - 2 1/2" (A & B) strips and
1 - 1 1/2" (Ca) and 1 - 1" (Cb) I did this by taking 1 - 2 1/2" (C)strip and cutting it into 2 uneven strips. I tried it this way & it worked fine. You can cut the C strips into any size you want. The object is to make them uneven. If you have any questions pm me. Unfortunately I no longer have my sample block, as I gave the quilt away & this was one that I failed to take a picture of.
