This is how to use wooly nylon thread! It’s more expensive than normal thread, so for most use cases, you really only need it for the lower looper thread for both coverstitch and overlock/serger machines! You can use it for all coverstitches, chainstitches, and to have a more full look on overlocked & merrow hems. You can also use this in a normal sewing machine, but definitely test the tension settings first. LMK if you want to see a video on how to use this on your serger! #sewingtips #seamstr
