Love it. Can you connect them together?
I don't think you could connect them easily. However...the ruler used to make these comes with a bunch of patterns for fans & circles; I think you could get a neat effect by combining this technique with one of those patterns. Or you could just back one of these tops with a fusible & applique it onto a background. If you made two spirals like this, and didn't sew the center seam (where the two halves join), I think you could applique them around a coordinating center square and end up with some pretty cool effects. I've been kicking some ideas around mentally...maybe one of these days (after the holiday) I'll actually try to implement them.
