I have a question. For 7-1/2 years I was involved with QOVs and have found a small collection of 4 patches in navys/turkey reds/tan prints from these projects. I also have 4 patches in just navy/red. There is a lot of variety in within these colors. Could these be used for these 4 patches or should I put some of them aside the introduce more colors? Just trying to use the units that are already made, however, I also have a collection of scraps like many of you. Opinions please. -- Also, this is my first mystery quilt.
