I had the opposite situation when I said I would make a memory quilt for a dear friend who had recently lost her husband. A box of the dreariest old flannel shirts arrived a week later with mostly gray, brown, black plaids and stripes. I didn't know where to begin. Long story short; I made a version of a rail fence, then added red sashing and borders. I thought it was the ugliest quilt I had ever seen and didn't want to even send it. She has written 2 letters and called to tell me she was delighted. Absolutely thrilled with this quilt. (She sent a picture and I'll try to post it later.)
Moral of the story: Beauty is in the eye of the beholder. If this young lady loves these colors that IS what matters.
Good luck.
