A stitch regulator is a costly add on to using a frame mounted machine. It coordinates the speed of the machine with your speed of moving it so the stitches come out even. If you're using your machine on a tabletop, just give yourself time, time, time. It takes a lot of practise to get really good a FMQ, but once you get the hang of moving the quilt smoothly, you'll see your stitches improve. Hang in there. If you want to practise on less expensive quilts, just use preprinted panels, quilt them up and give them away! The recipients will love them, not care if the stitches are a bit wonky, and you can chalk it up to practise!
