As of yesterday evening, I am the (middling) proud owner of a (mediocre, but functioning) model of a warp-weighted loom.
Well, to be honest, it's not completely finished yet - I need to fiddle with the position of the heddle rod brackets a bit more before fixing them.
It was made out of scrap wood that was hanging out in our basement plus two Y-shaped pieces of hazel wood, straight in from the garden. It's even set up already, and I have woven the first few wefts.
As you can see, the starting border is totally out of dimension in comparison to the huge loom size (about 30 cm width), as is the rest of the weave. That is the problem with models regarding textile - it's very hard or impossible to scale down the actual textiles, and that changes the overall look of both production models and garment models. In case you ever wondered why a small doll dressed up to model a set of garments looked ever so subtly wrong, that is probably the reason: if you don't scale down the fabric itself, the drapes and folds will be too large and too stiff.
In my case, however, that is irrelevant - I only want the small model to take along for workshops and seminars, to be able to explain the basics behind weaving and warp-weighted weaving. So scale, in this case, is not the issue.
(The starting border and weave is that narrow for a reason, by the way - not only because I wanted to save time in setting up the loom. It's the start of a form-woven tunic. I do not expect the piece to ever see the day of actually getting the body of the tunic added in... but it could happen. Theoretically. One day.)
