I love to make stocking hats - it's great therapy for me. Especially on cold windy days with the woodstove blazing away. My original Knifty Knitter set did not come with the yellow loom, and I found my hats were not working for a large portion of my community....so I got this and the purple loom. Now, I can make small, med, large and ex-large hats everyone's happy. Of the different style and brands of looms on the market, I find that Provo Craft has the best of the best.
If I were going to ask Provo Craft to make any changes to these looms, it would be to make an 18 peg loom with the pegs closer together than the large looms.
I recommend all of these looms but wish I found the yellow one sooner.
