timtex has been around for years---it is what is used to make baseball hat brims stiff-
when my daughter got married 10 years ago she wanted 64 fabric bowls-for her tables to hold pillow mints---i used timtex (still use timtex) for making bowls and boxes.... i managed to get them all made---and she didn't even get one---people at the reception took every last one of them!
