TomS,
i find that bucktails tend to be the worst culprits for stinky tying materials, other problem can sometimes be a moth/beetle infestation...that can ruin your day real quick, go an get some rubbermaid containers sized to accommodate your materials, for instance try to keep all your dry fly capes{necks} and saddles {dry fly}in one container in thier original zip lock bags take two paper towels an place on the skin side between the cardboard and skin ..make sure air is out of the bags and zipped closed completely.
next time you are at staples buy a labeling machine like a brothers p touch an label you boxes accordingly, also do this for your wet fly hen capes and saddles, bucktails ect. try using moth crystals inside of each container an periodically replace or add more crystals,you can also use cedar chips ,flea collars from pets ect to keep the bugs out, cedar adds a nice scent compared to moth balls/crystals ..but IMHO moth crystals/balls work the best.
also keep your other materials in boxes an label em..makes for easier location and also when putting em away.
you can also buy a small bottle of essential oil in your favorite scent..like lavender or balsam spruce..even cedar oil and put a few drops on a unscented bounce sheet and yer room will smell awesome.
hope this helps
