I've not had problems, but I have a friend who really struggled with quilting a batik top on her longarm. She researched the internet and found 3 suggestions that seemed to help most people: Spritz it with water, fabric softener, or silicone spray. She started with water, and that didn't help much. Then she went to the liquid fabric softener, and that helped a bit, but she was still getting skipped stitches. Then she spritzed with some silicone spray and that did the trick. She wasn't sure if it was just the silicone or a combo of the fabric softener and silicone that worked, but by that time she didn't care and was just happy to get it done!
