Does anyone know how to dye silky fleece? It is 100% polyester so it doesnt accept dye or maybe soemone has some blacklight colors I can buy?

Julie over at Out of the Box Puppets normally carries some black light reflective fleeces. http://www.outoftheboxpuppets.com/

Do a search on dying fabrics.  We've had this discussion before.  You have to use a certain type of dye on polyester.
What color(s) fleece are you looking for and how much do you need?

Www.aljo.com has a florescent yellow for polyester, but I have never tried it.

I have not found any other florescent dyes for polyester, only nylon.
