I just got a used Rigid Heddle Loom that looks like it probably wasn't that expensive to start with. The instructions are pretty hokey and don't say anything about the yarn that the heddle is meant for. So my question is: how can I find out what kind of yarn to use for the warp? Is there a formula I can use with the measurements of the heddle?
The holes are pretty small, so I assume that the yarn would need to be quite small, but I'm not sure HOW small I need to go!
