The pattern is in Better Homes and Gardens Special Interest American Patchwork & Quilting, June 2011 issue.
It was called YO-YO ROWS on page 65. If you can't find it anywhere, send me a PM with your address and I'll mail it to you. It was so much fun to make.
The original YOYO quilt I made was from that pattern and I just worked the Yellow one as half the size. It was so easy.
