One of the things I dislike about sewing the most is the scant 1/4" seam. It's hard to get a perfect 1/4" every single time, and then to put a scant on top of it...whew!!! I do my best but when they can't even make the foot a correct 1/4" (and I have 3 that aren't), how do we fumble our way around with tape and moving our needles and using our measuring tape to try to get the elusive "scant 1/4"?
