This accessory hems the fabric and at the same time sews an elastic in the hem.
With the help of the screws on the folder, you can easily adjust how much the elastic should pull the fabric together.
Fits almost all sewing machines and overstitch. Attach with screws (not included) or putty / sticky-stuff !
Best suited for woven fabrics. Requires some practice 🙂
For best result I use the same width on the elastic as on the hemmer
