The first warp for my new loom was a rug warp.
The first warp was a heavy cotton that I got from my grandmother who had been using it to make rag rugs. It was also recommended by Schacht for helping to clean the manufacturing oils off of the reed.
I measured enough warp ends to fill the reed. The reed that came with the loom is a 12-dent reed. That means there are 12 slots per inch. It’s a 37″ reed which means it has 444 slots.
I filled most of the reed with one warp end per opening in the reed. I read instructions and watched videos for warping front-to-back and back-to-front and decided that front-to-back looked like it would be easiest for me.
