Hi! I have a supplemental warp project on my 8 shaft loom. Supplemental threads are on shafts 1,2,3,4 and plain weave background threads are on shafts 5 and 6. This is a wide project so there are LOTS of threads on 5 and 6. When I lift shaft 5, shaft 6 pops part way up and when I lift shaft 6, shaft 5 pops part way up, so I’m getting a terrible shed. Can you offer any ad use on how to remedy this situation? Thanks so much!
