I want to share this idea for a homemade temple. I had used a gem clip with a weight hanging from it with my Bernat loom. It had rails on each side that the string could hang over. But then I sold the Bernat and got a Macomber loom. There are no side rails. So I had to come up with another solution. I had seen somewhere a bamboo strip bent and inserted into the cloth on the underside but I did not have any bamboo.
After playing around with the concept, here is what I came up with. I took a lease stick that is wider than my warp on the loom. I attached a jumbo rubber band on each end through the hole in the end of the stick and attached a large gem clip to that. I attach my temple under the warp and it holds the cloth out with just the right amount of tension while staying completely out of the way. It doesn't interfere with my seeing the fell line and it is easy to move.
I hope this will help someone else.
