Loom knitting is a method of knitting involving only 3 tools: yarn, a loom, and a hook. The loom allows for a variety of stitches to create intricate or simple designs. Beginners can very easily create amazing blankets by following simple steps. Looms are available in different shapes and sizes to aid in creating a wider variety of items.
I started loom knitting about a year ago, and I've used the KB Afghan Loom to create 6 afghans and 1 baby blanket.
