I have made a wall loom from a painting frame. I wanted it for my sheep farmer family that I am planing to do. It is fare from perfect but I like it just the same. Your crafty modern sims might like it as well. It if of course totally CASt-able with three recolourable parts.
Warp-weighted looms have been found dating back to 5500 BC. The loom consists of a heavy frame with a roller beam on the top. The warp is attached to the top beam and the tension is held by weights at the bottom. The weaver usually stands and weaves from the top towards the bottom. The weft is beaten upwards.
