The good news… when my son was in 3rd grade, his class did a super fun & educational science unit on crayfish. The bad news… my son was one of the “lucky winners” who got to take a crayfish home at the end of the unit, and it lived FOREVER. This pattern (with its cable stitch on the leg that looks like a crayfish claw) is written in memory of the 3rd grade crayfish. May he rest in peace. The 3rd Grade Crayfish Socks are worked top down and both written directions and charts are available.
