Quick Quilt

Here are just a few sample blocks of a great quilt block that my friend, Molly introduced me to years ago. It's the "Double Pinwheel" and by using various contrasting fabrics, you can get two, yes I said two quilts from this one process. I call it the negative - positive effect. Anyway, this quilt can be made in a matter of a couple of days and striking results. Everyone will think that you have spent hours and weeks making the two.

I don't remember which quilt magazine or book this came from......does anyone recognize it?
