Does this ever happen to you?
You are weaving away on a wide inkle warp and it slips off a peg.
I have this affliction which causes me to design inkle warps that end up wider than I intended resulting in warp slippage.
The beauty of using rubber jump rings is that they are available in so many sizes and fun colors; plus they are fairly inexpensive. You can purchase them almost anywhere that sells jewelry making supplies. Or you can go to your local hardware store and get some rubber o-ring washers. I think they are in the plumbing section. Unfortunately, the ones at the hardware store only come in black, which is not nearly as fun!
warp, weave, be happy!
