Okay, so I'm trying to sew along, minding my own business, and all that, but sometimes the feed dogs just stop moving the fabric. They go up and down and forward and back, but the fabric doesn't move. This usually happens when working over a seam allowance, but sometimes it also happens at the beginning of a block with only two layers of fabric! It makes an ugly knot and pulls at the fabric, and sometimes it even pulls the fabric down into the needle plate so bad I have to cut it out!
Does anyone know anything I can do to make it work? I figure a walking foot would probably help, but I just can't afford it right now .
Thanks in advance,
Sloan
