Hi Sara and Heather, The bolts I used provided enough tension, even with a very long warp. I had started with film canisters filled with pennies and when I ran out of pennies, used various screws and washers in the canisters. That was my experiment for how much weight I needed for the 10/2 cotton. Actually I started with weighting only the selvedge threads and had the main group of the double faced weaving tied onto my inkle loom. By playing around with the weight in the film canister I could match the tension of the part of the warp tied down on both ends.
When I switched to using one film canister per card and a warp of 40 cards, the canisters were all bunched together at the back of the weaving and almost impossible to deal with individually to work out the twist in the threads per card. That's when I got the hex bolts, which are long and hang straight down nicely. The weight bolts I used did not hold the warp under extremely tight tension, but that is what I wanted. I was doing calligraphy and when the warp is too tight the letters get too elongated. So when I beat after each pick the warp gave a bit, but not enough to make the weaving loose. Hope this makes sense. Nancy
