If you tie in any real numbers, definitely get bulk skiens from somewhere online. I was at BPS today and their chenille is absolutely ridiculously priced. A small thing of chenille (on the cards) is $2.29. Thread is well over $1. They get it though if you want to buy in person or don't know about the online places, since there aren't any other fly shops around. But they don't really have a fly shop...just a bunch of random fly tying materials...

Anyway, what kind of sparkly stuff do you want? Silver tinsel or some of the special colors? For the better varieties that I've found check barlowstackle.com and jannsnetcraft.com.
