I haven't really looked into it very much but I have people come in at least a few times a week asking if we make vinyl stickers for windows or whatever else they'd use it for. I tell them we can't and they go about their business.

Is there a material that is durable enough to be a replacement to vinyl that's safe for me to cut?

I know with proper ventilation and quick passes I can cut vinyl but it makes me uneasy and I don't want to have any warranty issues.
