LadyRags, I have spent the past month making a quilt for our spare bedroom. I am using reproduction fabrics in grays, blacks, browns, blues and golds. I cannot STAND these colors or prints! I am using them because DH likes them and he has made gorgeous Shaker furniture for that room. Yesterday some members of my guild saw part of the quilt and they love it. Those colors are just not for me. Every once in awhile I have to make a little something with purple or red for a break. As my mother always said, "This, too, shall pass".
You can do it, it will only be for that short time and you will be helping your friend. Think of just how much she will appreciate your help and she won't even know exactly what it "cost" you!
Best wishes!
JoAnne
