In my never-ending quest for something new to do with my looms, I found this fascinating tutorial which shows you how to make crochet-look granny squares using Knifty Knitter Looms.
With just a 12 peg and a 24 (or larger) peg loom and some yarn you are able to crochet. Of course as with regularly crocheted granny squares, the colour combinations are unlimited to make your squares interesting and unique.
