I'm making a 'watermelon' log cabin quilt top for a friend that we are exchanging the labor on another project. The finished top will measure 63 x 69.
Since we are trading 'labor only' she wants to reimburse me for the fabrics and I don't know how to figure that out. I've used a bunch from my stash and have bought a bunch to have a nice variety of colors.

I thought I could go to EQ7 and figure it out, but No.........I've not learned it well enough.

Any master minds out there that can help solve this problem????????? Please, I need your input.

Thanks for all eternity!!!!!!
