Hello, I am a beginner and have a question about sagging threads. I have an old Leclerc Fanny loom. I followed Jane’s instructions warping back to front. I got my warp tied onto the apron of my cloth beam evenly and securely. I thought I had even tension but as I lifted shafts 1-3, I realized that there is no tension on the bottom, all threads were sagging, the upper level was perfectly normal. It happened again when I lifted shafts 2-4 -my threads on the bottom were sagging and the upper level was perfectly normal.
What did I do wrong? How can I fix it?
I would really appreciate your help.
Thank you in advance
