I'm using my walking foot and can't locate the 1/4 inch. I don't usually do my own bindings - when I do I do it the simple way- folding the backing up over the top. I've done a regular binding a couple times before but at least a year ago. I just sewed on a placemat binding using the outside of one side of the walking foot as a guide - thinking the 1/3 or so seam allowance would be ok. It's not. Gosh golly darn - you'd think I'd learn. Can anyone advise before I fall asleep in this chair. Thanks
