Congratulations, it’s a peg loom! This type of weaving predates the Vikings.

Pegs are set into the holes in a board.
Weft strings are laced into the pegs.

Then whatever you’re wanting your rug to be made from, for my first one, I’m using plastic grocery bags looped into a rope. It is wound alternately around the pegs.

That’s as far as I managed to get today. But I’m very excited to try this… I have rugs and maybe even saddle pads in my future! I’ll be letting you know.
Find me here!
