Dritz - Fray Check
Do not be caught off guard. Even some of the best-felted wool will fray. Some wools are prone to fraying because of a loose weave. Do not be stuck without a quick solution right in the middle of your project.
Fray Check can help you, making for a nice, crisp look for that fraying piece. Fray Check is to be dabbed or glided on the edges of fraying wool. When it dries, it creates nice, firm edges for stitching.
Are you concerned that a narrow pointy piece of wool will be split by your needle? Fray Check will make a quick fix and will help keep that point...pointy. Fray Check is another tool for every stitcher for excellent outcomes.
