Folded Hem Attachment for Sewing Machines

I needed to sew a whole bunch of folded hems for my DIY hammocks and other outdoor gear. Some materials are hard to iron and shouldn't be pinned. This folded hemmer attachment helps tremendously. When I first designed this I didn't have any presser foot that fit my old but trusty Singer 201K, and even now when I got a whole bunch of them I find the printed ones easier to use.

Hem width, length of guide channel, position of mounting holes etc. can be easily customized to fit just about any sew
