I ran across this site the other day and just wanted to share it. http://www.miriammilgram.com/exhibits/ob_index.htm
There are a number o interesting patterns and also photos of the looms some of the old-timeers are still using. The community is in Oregon and consists of three seperate communities who emigrated here from China. After the Bolshevik revolution many people fled West but as many fled East through China and eventually made it here to the US. From tthe photos they appear to use a numbr of different looms from backstrap looms to an unusual arrangement that appears to be a counter balance loom with weights attached to balance the weight of the shafts. Some appear to hang from the ceiling and there is at least one home made stan-alone loom.
Bolivian Warmi posted regarding the Old Believer's belts that she had seen and I hope that there have been some samples by now, maybe even completed items.
It is interesting the different techniques used in cluding weaving, plaiting, card-weaving, and a "hidden" technique (potainoi, which actually translates into secret technique) and even sewn belts. The bottle belts, which I'm not familiar with, appear to be woven as a tube. Check out the pages there are photos of designs some of which are pick-up and there are variations based on location such as the Bulgarian and Slovak types. There are also a number of videos on the site. Enjoy!
Happy New Year everyone and best regards, Charles
