Well...I asked the question - so now I have to answer! I've got tons of looms.
Knifty Knitter long and Circle and an extra small
Knifty Knitter Flower Loom
Knifty Knitter Purple Long Loom
Authentic Knitting Board - 28" and 10" Boards
DA Wondersock Loom
DA Baby Afghan Loom
Pocket Knitter
Knit Wit
Spool Loom and Straw Weaver (not pictured)
Two unknown origin wooden circle looms - hand made that I got at a thrift store
and last but not least I have a new Markman Farm Adj Loom coming that I won in the Early Bird Drawing for the pattern writing contest.
My most used loom....hmmmm....that's a hard one. I use my AKB 28" board a lot, especially lately. I use my Knifty Knitter Circle looms a good bit too. My DA looms are very new so I haven't used them to their full potential yet. I plan to add a loom review section in the loom resources soon, please add your comments too!
