From the book:
“Featuring granny squares that are joined as you go, this afghan is super-easy to stitch. Each block is made up of nine squares in alternating colors to create a patchwork quilt effect. Worked in rich contrasting hues, the wrap is finished with a scalloped edging.”

“Entire Afghan is worked holding two strands of yarn together”.
