In weaving the turned monk's belt, I was having difficulty getting a nice shed to open because the warp is so dense. The pattern warps also would sometimes sit on the "wrong" side of their companion ground warp which would put a spot of color in a position that I think doesn't look right.
I developed a sequence that helped me get through this problem. Instead of using the tie-up as provided, I tied up the pattern shafts as a direct-tie, and the shafts that weave plain weave separately, plus a treadle to lift all the ground threads together. So for each change of pattern block the weaving sequence is:
1. With the beater at the fell of the cloth, lift just the pattern shaft for the pattern you need to weave next. (Opening a sticky shed with the beater at the fell gives the yarns the best chance of opening cleanly since there isn't the extra interference of trying to move through the reed.)
2. Push the beater back. Clear the shed with a sword, bringing the pattern threads up to the fell so they sit up above the cloth and in between the proper ground threads.
3. With the top pattern threads still raised and the beater again at the fell, with the other foot raise both ground shafts.
4. Push the beater back and repeat the shed-clearing with the pattern threads that are on the reverse of the fabric, so they sit down below the cloth and between their proper ground threads.
5. Lowering the ground threads but leaving the top pattern threads still raised, weave however many picks are required according to the treadling pattern.
This is slow going, but I was such a happier weaver doing it this way!
