I am encountering an issue with warp tension while weaving damask with half-heddle sticks. Several warp threads, all where the pattern is (most in the center), have become loose which is resulting in an unclean shed on several, but not all, of the treadles. I have weighed the loose ends but new (or the same it's a bit hard to tell) ends have become loose. I would appreciate any suggestions on how to correct the issue.
I am weaving a 6-end broken twill with 8 half-heddles (Wreaths from Weavers' Delight) using 16/2 Unmercerized Cotton in the warp and weft sett at 40 epi on a Glimakra Julia Countermarch. I am using elastic bands on the shafts and have tied all the lower lamms to the outer treadle which corrected an issue I had previously with floating shafts using this method (thank you to Joanne Hall for these suggestions).
