I have learned that fan folding the quilt so the entire weight is close to the needle is very helpful. Once I have all the weight within about 16 inches to the left of the machine, I then fanfold the other direction and put it on a small table that fits under my left elbow.. I make sure the area behind the machine is clean and smooth. The quilt then has nothing to drag or catch on, and I can smoothly feed the quilt into the machine. I hope this makes sense. It's what works for me, and I'm able to do king size quilts without any pain.
