Applied sparingly to a spool of thread or bobbin of thread makes machine sewing smoother and hand sewing easier. Sewers Aid lubricates the thread guides and tensions as it passes through the machine. Eliminates skipped stitches in sheers and knit fabrics. 1/2 fl. oz. bottle.

PLEASE NOTE:  Do not use on machines with automatic thread tension.  If silicone gets into the tension assembly it will create problems with the auto tension mechanism.
