Need help with quilting frame slipping
 

I have a Grace handquilting frame and when I set it up the frame itself starts drooping. I have all the dials tightened as hard as I can by hand. Any advice would be appreciated.
Thanks!

If it is in need of a sawhorse, you can get real sturdy ones at home depot.

It is not drooping in the middle. It is hard to explain...Let's say I set it up to be 24" tall, then both sides begin slipping so it goes closer and closer to the ground.

I don't have the Grace frame either, but it sounds like you are missing some hardware. If you still have your directions, you might check to see if you are missing some lock nuts, etc. You can also call the Grace Co. and tell them what it is doing and they may be able to tell you right away what you need or need to do.
