So I found this loom on eBay last weekend. It wasn't really an impulse buy; I've been looking for a tape/band loom similar to this on and off for months. So it took me about five seconds to hit Buy It Now!
There was a project already on it when it arrived yesterday. I finished it this evening. I love using this loom!
It was made by F. Ellmauer from Cedarburg, WI. I haven't looked the maker up yet. It was, according to the seller, made from plans published in a Latvian newsletter about Latvian Belt Looms.
