I've been trying to learn more about color and the color wheel. I bought the book "Color For the Terrified Quilter", which I like, but I will never have the time to do all the projects they have to practice and the mock ups with fabric glued to paper. I just won't.
So I've been doing something else to practice color combinations and get a better handle on this.
I print out quilt coloring pages that I've found for free online (google "quilt coloring page") and then pick a color combination and color them using those colors (crayons or colored pencils, which as it's the beginning of the school year, are cheap now at Wally World). Yes, it lacks the zing of print fabrics, but it's a lot faster and cheaper, and I can spend time coloring with my kids and also indulge my quilty side.
