J, If you are collecting the skins yourself, just skin them and tack them to a board, flesh side out and dry them. Be sure to remove and excess tissue that may have stuck to the skin. After they are dry, usually only a few days, you can remove them from the board, roll them up and store in a dry place...or you can put them dirrectly on the bow green once you have skinned them. Either way works well. You do not need to tan these skins but you must remove the scales. The skins will have to bew dry to remove the scales. You can use Tite-Bond glues or hide glue to stick them to the bow. Pat
