I had originally bought a square loom, a rake loom, and a round baby hat loom in 1/2" gauge, but quickly came to realize that I needed more round looms since I knit mostly hats, and the round looms are so versatile for other projects also. The round shape is easier to hold in my hands as I knit, and I like the 1/2" gauge. It has a smaller stitch which allows for the use of a single strand of worsted yarn without being as tedious as the smaller 3/8" gauge. I bought 4 assorted round looms, and they are already getting a workout. Love them! I highly recommend Cindiwood looms!
