Has anyone ever used the template plastic from Jo-Ann's? I looked on their site & I see that they offer several different ones. I'm going to make a cell phone stand & the instructions show covering cardboard for the stand but I want to use plastic in case it gets wet the inside won't fall apart or warp out of shape. None of the products below tell the thickness of the templates but they all say they can be cut with scissors, rotary cutter, etc. My pieces need to be sturdy enough to stand up but not thick like a rotary ruler. Any suggestions on this for me?
