When my son was in high school I did Trip Around The World for him in his favorite color, orange. He's in his late 20s and still loves the quilt. I backed it with flannel. He's a cuddler. I collected orange for about a year as my stash had little. It was a wonderful exercise in color and I was amazed to see it went from near yellow to near red. I can now see the beauty in each color when you look at it in it's full range.
