When it comes to tying materials, it pays to fish for deals
#2 Arts and crafts stores
Years ago, I took my young offspring shopping for art supplies at our local craft superstore and came home with bags of goodies for myself, as well. Craft shops stock a wide variety of feathers, though you have to watch the prices, especially compared to dollar stores. However, you can often find deals on beads, tinsel and wire, as well as chenille, embroidery thread (for bodies, not tying) and fuzzy or sparkly yarns that make very interesting streamer and nymph bodies.
Arts and crafts stores are also where I get closed-cell foam sheets, cylinders and chunks that I use in my bass bugs. And I’ve had good luck with brightly coloured synthetic craft fur as a body dubbing, especially on saltwater flats flies.
