A few years ago, I rediscovered potholder looms after having neglected them since my stepdaughters were twerps. I had been delighted to rediscover them then after having enjoyed them in my own childhood, and have been enjoying them anew in recent years.
For a while, I moderated a discussion forum dedicated to them, but discussions were rare and spamming attempts were common, and that is now gone.

By far the most common questions are about loops and sources.

I get most of my stuff from local stores, Math 'n' Stuff, and Top Ten Toys, with the occasional order from Klutz supplementing.
My own Amazon storefront has my choices of tools and supplies. I get a few cents if you order there, and more importantly, I get some measure as to how much interest there is in what I am doing here.
Potholder loops were originally byproducts of sock manufacturing (trimmed off after closing the toe), and many of the budget bags still come from that source. These loops tend to lack consistency and can be difficult to make nice potholders from. Harrisville and Klutz loops are custom made for craft use.

Potholder looping is primarily a therapy activity for me. I have found it very beneficial, and the recipients of my potholders seem pleased with the results. Many of my potholders have been sold at charity events.
I welcome comments and topic suggestions, but am usually unable to provide individual responses.
