This quick, fun cowl can be made on any 3/4 gauge loom with at least 24 pegs. The sample was made on the Yellow Knifty Knitter.
Any bulky weight yarn should work, the sample was made with Black Sheep DyeWorks Bulky Superwash Merino.
I am a bit of a lose knitter and I used approximately 130 yds. Choose something that can be blocked as a nice light block opens the lace and sets the stitches.
