I have been weaving on the Schacht Arras tapestry loom for several years now. They have released a stand and treadle assembly for the loom which I have been using for most of a year now and I really love it.
The treadles don’t work without the stand so you do have to purchase both the stand and the treadle assembly to make the whole thing work. The treadles are manual meaning that they work with a pulley system and don’t need to be plugged in. They glide easily and are very quiet.
