Once while doing a quilt with my walking foot I thought a decorative stitch would be nice. So I switched my machine to a decorative stitch and it worked. The next time I tried to use it I realized I had ruined my walking foot because the little arm doesn't want to stay on the screw that sticks out the side where the needle attaches. Most of the time it stays on but once in a while it pops off. I'm not spending another $75 on another one for my machine. I will just live with the one that I ruined.
