Slack section in the warp.
In the lower left area of this photograph there is a section of the cloth that shows an area of uneven beat. This section goes slack everytime I advance the warp.. I have tried advance every few inches, put a stick under the section at the back beam. For the first time ever I have put a bungie on my overhead batten. To help my arthritic thumb joints. I wonder if I need a second bungie on the other side to have an even “pull” on the batten? Going to try that now. Wish me luck. Thanks for all of your advice.
