Part of small collection I’m working on - easy retro scarf patterns to be offered as part of a scarf kit promotion.

This stitch is a variation on a classic granny square. I’ve seen it called Brick Granny Square (Robyn Chachula’s Crochet Stitches VISUAL Encyclopedia) and worked flat as an overall fabric. I’m also told that it’s called Candy Box Granny (thanks Ellblo!). In this case, the scarf is crocheted as a single piece in the round.
