This is a twist on the inspiration card for the Case Study challenge (see link below). I used scalloped circles cut out of cardstock and wrapped in 3 strands of embroidery floss. I love the designs that are made. The more space you skip when you start wrapping, the smaller the circle in the middle will be.
You can use any shape for the Spirelli designs, but I like circles and ovals the best. It does not have to be a scalloped shape either. I have used circles with spokes on them from the Cricut Accent Essentials cartridge as well as the shape from the I-top Brad Maker punch. The more spokes or scallops there are the tighter the design.
