Mary, I haven't started this one yet, taking time to breathe after getting #14 done. I think what I am going to use is the plaid will be A, green is B, red is C (or I might use a tiny print for this, mostly red with some white) and the lower right is D. I think the upper right will be the border, and not sure about sashing, might be that dark print.
Yesterday when I was finishing writing the instructions for today, I went in and labeled the Christmas prints, but looks like I pulled the wrong one from the pix file.
