The setup in the pictures shows how to handle different types of warp. For the Anglo-Saxon band all cards are turned in the same direction all the time. Because this generates tremendous twist buildup I tied the four threads of each card to a tama and spread the warp as far as possible. Periodicaly I lift up the warp bundles, one at a time, push the twist towards the tama, and let the tama do the untwisting.
Tama are nice but pricey. There are less expensive alternatives that work just as well. Some are:
It is rarely necessary to weight each card separately. In the last example the black/white warp is woven in the double-face technique and has no twist buildup. Therefore a simple heavy weight (water bottle) can be used for all cards. A bag of pebbles would work as well. There are five cards with green warp threads are turned in the same direction for the full length of the piece. They are weighted individually using film canisters of 30g.
If I use bobbins (of any kind) I tie an extension (red thread)
If a portion of the warp is tied up as a big bundle it can be tedious to spread it out. Here comes help in form of a beauty comb.
It is not a matter of cards, rather a matter of yarn. The flat part of the handle is 3 1/4 inches wide, the spiral is 9 inches. If you use, let's say 20/2 perle cotton you can use 80 - 100 cards and get a band that is 3.5 inches wide. If you use 3/2 perle cotton you would use approx. 40 cards for the same width. The spring/back beam is not a limiting factor.
Tama, 75g for each card
Insulators, 50g for each card
Water bottle + 5 film canisters
- porcelain electric fence insulator; small ones 50g, larger ones 75g
- film canisters filled with pennies or marbles (30g here)
- fishing weights (I have none)
- washers or similar objects found in each hardware store
on each bobbin. This way I can reduce loom waste. In this
example I only wasted about 3" of the warp.
