You can get creative and make your own string silencers. About 40yrs ago I bought a skein (thats a bundle) of kniting yarn. From recurves to now-a-days that is all I have ever used as string silencers. They do work great. Cut 10 to 15, 4" pieces, tie them together at center, open or spread bow string and pull half way through. Only real drawback is that stickers collect on them. But can be combed out or just replace.
never say never
