I need a source for bolts of flourescent fabric (wholesale supplier).  Have a group wanting to provide puppets for missions.  I need to keep the cost as low as possible, (will donate my time) so must find wholesale suppliers. I know we have kicked this around in the past, but I can't find a wholesaler listed.

Try this google search
Google Search: new york fabric wholesale
Actually when I did the search this site http://www.nickoftime.net came up.  They are not New York but seem to have a pretty large selection of stuff.  The only thing is I have no idea if any of it is florescent. 

The reason I suggest searching for New York wholesalers, is because of the garment district there.  There is a reason the costume and fashion designers do all their shopping there.   You can find stuff that you just can't anywhere else. Who know what type of price you'll run into though... it is New York.

Just some I found via search other then NY.  The second one looks like it may be the holy grail.  They had 214 fleece swatches 66 of which where solid.  Saw a neon orange but as we all know that does not always mean it well react to black light.

I have a list of suppliers and a lot will sell wholesale if you buy a certain amount................... as for as black light if they don't have it maybe they can suggest where you can get it. i don't buy much of that type fabric.
