This is a piece of cotton yardage. The warp is 10/2 unmercerized cotton alternating with a 2-ply handspun cotton yarn. The weft is a handspun cotton single.
The loom is a tag sale purchase that was originally used for making belts (think inkle loom with a texsolv heddle). I've tried to stabilize the texsolv heddles with a row of crochet stitches on top and windings of yarn at the bottom of the heddle frame. The warp pulled in 1.5" when I started weaving, but seems pretty stable now that I have a few inches woven. The fabric is light weight enough for a shirt!
Durable: A new pair of bed socks from 100% acrylic worsted weight yarn. My last two pairs lasted 4-5 years!
