진-아-마-지그

I've been using this for hemming jeans and it finally lets my machine glide over those thick cross-seams without skipping stitches. The little metal guide does exactly what it promises, saving me from hand-cranking over bulky spots.

After wrestling with thick denim hems for years, this little tool finally lets me topstitch over bulky seams without the needle skipping or the fabric bunching. It's become a permanent part of my sewing kit.

The little metal guide sits right over that thick seam, so my needle glides instead of catching. I finally finished hemming a stack of denim jackets that had been sitting in my project pile for months.
