I made another set of pot holders, this time with a walking foot.
Pattern: from One Yard Wonders
The walking foot really helped keep the top, batting, and backing in alignment as I quilted. I think the tension needs to be adjusted, though. It seems to be a little bit different than when I sew with a regular quilting foot. I intend to use the walking foot for a few quilts soon, so I'll do a few more practice pieces before I start on those.
