Towel #12 - 4-Shaft Tricot

This 4-shaft tricot has a somewhat similar look and feel to the crepe weave but it has ridges and troughs in the fabric instead of the random pattern of crepe. They don't show up as well in the picture as they do in the fabric. It's another nice fabric.

This one is in 8/2 cotton sett at 16 epi with green warp and tan weft. It is threaded as a straight draw - just 1,2,3,4 repeated and the tie-up is plain weave with a third treadling of (1,2) added. So, it's (1,2), (1,3), (2,4) and the treadling just repeats the three in sequence. The ribs are formed because the threads on shafts 1 and 2 form small warp floats that are offset by one pick so the effect is that you get two threads with warp floats (a ridge), two without (the valleys), then two more with (another ridge), etc.

Here again, if you've been reading my earlier posts, is another structure that you can weave with a straight draw on a 4-shaft loom. This is great to know for times when you either feel like putting a really long warp on the loom or when you have some warp left over after a project. You can just change the tie-up and you can go from plain weave to basket weave to twill to point twill to tricot, etc.

There are other tricot variations, all of which produce ribbed fabric.

I finished the project on the Dorothy today. Once I figured out the trick about the long shuttle I don't mind weaving on the table loom nearly as much as I did before. I still find it pretty easy to lose track of where I am in the treadling sequence. I don't seem to be able to get into the same kind of rhythm that I do on a floor loom where most patterns settle into a nice routine after a short time. With the floor loom, you only have to remember which treadle to push but on the table loom you have to simulate the tie-up with your finger for each pick. You also have to put the shuttle down when it is on the right side of the loom so you can use that hand to change the shed. This may be one advantage of having the levers on the front of the loom as in some newer table looms - you don't have to put the shuttle down.
