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

Have you double-checked to see if you have a straight line from the treddles to your shafts? Sometimes if only 1 tie-up isn't on the right path - it can cause you grief.

Is your warp coming up from the warp beam and then over the back beam and into the heddles?

Agreed! I had the identical problem this summer with my Dorothy. The instructions on how to fix it are somewhere on this site, but if I remember correctly,: with the Fanny you can just remove the back beam, slide it under the warp in front of the warp beam, and then raise it up and re-attach it. It was a little trickier with the Dorothy because the back beam is fixed.

Thank you, Ladies, so much! My warp wasn’t coming over the back beam:) it was easy to fix.
Very grateful for your help😊

Marina,
I'm so glad you had an easy time fixing this.

Ask me how I knew that was the problem LOL...
