To get started, dig into your scrap pile, stitch a few fabrics together, then trim into a diamond shaped block! (My son's former 1st grade teacher would argue that this is a rhombus, but we'll just stick with diamond. Sounds prettier) Jan's got all of the details, but the main point is to have fun!
Stitch Organic scraps from various projects, just waiting to be diamond-ified.
Will these 4 end up in a quilt together? Maybe! Who can say? Anything can happen with improv, right? And there's no reason to stick with individual print collections. Just kinda went that way for starters. I'm adding my scrappy diamonds to the Lancaster Diamond Flickr Group, and you can too, should you decide to quilt along with us.
