This was the first of two scrap fabric rainbow projects I started over Easter weekend. I couldn't decide how to quilt this one, so the second project got finished first. A couple weeks ago I had run across this shamrock fabric remnant while organizing my fabric scraps. It was originally used for a St. Patrick's Day ornament for my grandma, and it lends itself well to rainbows. The back is just plain green and it's only quilted along the top and bottom of the rainbow strip.
