Marly Bird is back with another Game Day Mystery Make-Along, kicking off next Sunday, February 7th to coincide with Super Bowl LV. Choose to knit or crochet the mystery pattern over the course of the day. Starting at 8:00 am, a new set of instructions will be released on her blog every hour for 10-hours. Both patterns use two colors of bulky weight yarn (the designer used 252-yard skeins of Caron Lovely Layers Swirl Cakes) and size US 10.5 (6.5 mm) or size K (6. 5 mm) hook.
