My friends and I once saw a monochromatic purple rail fence quilt at a quilt show and we all thought it was the most beautiful quilt there! I stood in front of it for a long time, trying to figure out what made it so gorgeous. I finally realized what it was: she used every shade of purple she could get her hands on, not just lighter and darker shades of the same purple color. There were purples so light, if they were any lighter they'd have been white, and purples so dark they were almost black. There were reddish purples, bluish purples, pinkish purples, every kind of purple. So when my purple-crazy niece got a quilt from me, I made it just like that one!
