I have always shied away from fabric panels, mostly because I have never quite figured out what to do with them. Usually the blocks you can incorporate into your quilt have various sizes which require math. I like to sew, sewing and math do not go together (for me) and I have yet to embrace this idea.
Here is a picture of a fabric panel cut up and a heavyweight stabilizer put in the mini quilt sandwich. Unlike, paper flash cards, these will never get ripped.
Christmas will be here before you know it. This would make a toddler a nice gift and a little smarter. Win Win!
