It's also a super easy pattern!
I used a 10mm hook and leftover yarn, but obviously you could use any yarn you like.
Chain 120 (or to your desired length)
Row 1: Treble stitch in 4th chain from hook and in the rest of the chain.
Row 2: chain 3, turn, Treble stitch in back stitch only all the way down the row
Row 3: chain 3, turn, Treble in front stitch only down the row
Row 4+: Continue with pattern (Back stitch, front stitch) until desired width is obtained.
Finishing: When rows are completed, single stitch around border, tie off and weave in ends...or not, who cares it's a leftover scarf! I also stitched the two ends together, and then twisted it up and around my neck.
