One of the idiosyncrasies of the Knifty Knitter looms is that the manufacturer, Provo Craft, is constantly changing the color of the looms. Patterns written for the pink loom, or yellow loom, may not coincide with the colors of your loom, because of the constant color changing. A better way to identify a loom is by the number of pegs it has. A pattern calling for a 24 peg round Knifty Knitter loom, for example, will always be correct for your 24 peg round loom. My Knifty Knitter loom that has 24 pegs happens to be blue, but yours may not be.
The Knifty Knitter round loom set actually comes with 4 looms. The sizes are: 24 pegs, 31 pegs, 36 pegs, and 41 pegs. When you number the pegs, start by numbering the peg directly above the anchor peg with a 1. Move around the loom going clockwise, increasing the numbers as you go. As you knit in a clockwise direction, having your pegs numbered will help you.
