It's not just the warp tension. My picks need improvement.
In the past, when I wove on merino warps, I had three kinds of picks: "bang" for merino/mohair wefts that needed packing, "snug" for merino/mohair/silk mix that needed to sit snugly against the previous weft, and "space" for merino wefts where I wanted a space roughly the width of the weft yarn between each pick. And depending on the weft and the sett, my body controlled these almost automatically. Even when the picks were a little irregular, I was able to more or less disguise it in the washing/fulling process.
It doesn't work that way with the loose way I weave my cashmeres, and as for cottons, a far more disciplined beating is required, but my body hasn't learned the different degrees of control yet, and still I hate to stop/check because then there is no rhythm in my motion.
I said I wasn't grumpy or cranky tonight, didn't I? I think I'll go to bed before the Black Holes sucks me in.
