Do stencils go bad?

I had to stop giving glitter tattoos today at a festival I was working. When I pulled the stencil up, the design came with it. It was the oldest thing. I'm not sure if the glue was bad or the stencils were too old. Anyone have this problem? It was a NEW bottle of glimmer art glue. The stencils weren't that old...one was maybe a year old, and one about six months. Any advice? I had to refund money three times! Oh, and it was fairly warm out...my kit was pretty much in direct sunlight. Hubby doesn't think it was that. He says we've worked in hotter weather with no problem. Thanks.

No one??

I've had my stencils stick together and become unusable that were on my poster as examples. I think it might be exposure. Sounds like yours were fairly new though. But yes, I would get them out of the sunlight just in case.

Thanks for answering Denise. I thought about contacting the folks I buy my stencils from.
