pyrocreations had about 5800 feet of 1/16 inch fuse in stock a few days ago. That is not much (for them anyway), so they took it off their web site.
If you want some, e-mail Steve Gamble at pyrocreations ( pyrocreations01@yahoo.com ) and make sure he still has some. If he does, what he will tell you to do is place an order for the 2.2 mm fuse, and then tell him via separate e-mail to substitute 1/16 inch fuse instead.
They do not have a minimum order. Shipping is reasonable, but make sure that if there is anything else you need that you order it at the same time, as the shipping will be less in general per item if you order it all at once. They have lots of amusing stuff (the fourth of july is coming up). The flying fish fuse is lots of fun to play with (info on their site... it is cool stuff - i just "played with some" a few minutes ago and was impressed with what can be done with it.)
