I was having the same problem and having the foot not liking going over bumps like flying geese. I talked to an expert at the yearly quilt show. She said my machine had wide feed dogs and to replace my 1/4 in foot with an edging foot and adjust my needle to find 1/4 in. I havnt tried it yet but she was right about my foot not covering all the feed dog. This foot will hold the fabric better. Check and see if your dogs are covered by your 1/4 in foot.
