This is the quilt back of the Positive Quilt, I'm making for Amy. When I started thinking about how I wanted the back to look, I thought of circles, to balance the plus signs on the front. I've never pieced circles, but that's never stopped me, before. The front on the quilt uses 12 Kona solids, and I own a 30° ruler, so I figured I was set. 12 x 30°=360°, no problem.
When I laid out the circles, I didn't want them all lined up, nor all looking the same. I offset them and twisted them, to hopefully gain the feeling of movement.
This is a lot of fabric to wrestle. The quilt is 86" x 94", so the back is 92" x 100", I pressed as I joined but failed to press the whole back after completion.
