Tape Looms – Box Looms – Heddle Boards
I also make tape looms; often they are called box looms. The looms that I make have a workman-like quality to them. Some folks create very nice tape looms with a fit and finish that rival fine furniture; mine are more like folk art items for sure.
Here is one I made loosely based on the well-known loom in the collection of the Hershey Museum of American Life in Hershey, Pennsylvania. I made this for my girlfriend who makes straps for my horn work.
I will post what I have for sale here in the future.
