Prym fringes stop is a colorless liquid that prevents open fabric edges from fraying by strengthening the fibers – perfect for appliqué work, e.g. B.Needle Turn. When sewing circles, you can also apply fringe stop to the curves, which can then be easily cut before turning. The dosing bottle has a pipette-shaped opening for easy application, similar to a glue bottle. 22.5 ml fringe stop are included. The effect of the fiber-strengthening fluid can only slightly decrease after repeated washing. The treatment can be repeated as often as you like.
