How do you make plastic straws?

Ideas for a sealer to use on plastic cups, Is ModPodge completely waterproof?

• Hello everyone, I am planning to decorate some plastic cups. These are the type of cups: http://yardandpicnicware.biz/wp-content/uploads/16_Ounce_Clear_Acrylic_Tumblem_Straw_Cup_Reusable_Insulated_BPA_Free_Drink_Cold_01_uwp.jpg Of course they will be completely clear though. I will be doing the design myself. And I'll be ordering coloured reusable straws that match with he design. My question::::: What type of sealer and glue do I use? I'm thinking of getting some paper, printing my design on it, then using glue or ModPodge to stick the design on to the cup, but what do I put over the paper design to make sure it is waterproof? These will be going to other people, and I want to make sure they're perfect! ...I read something about PermEnamel... Can that go on the hard plastic of these cups? Can it be painted over the paper without ruining the ink on the paper? Does it dry on clear so my streaks of the brush do not show on the clear cup? One more thing: What sort of paper do you recommend I use? I have normal white printer paper, but I have a feeling regular printer paper won't cut it. What about the thin clear plastic sheets used for overhead projectors in schools? I can print color on to those, and paint over those without the ink messing, right? Thanks everyone!

• Answer:

  Modge Podge is not waterproof. I think the projector paper would smear also. Maybe adhere with mp then seal with clear, food-safe acrylic paint? Or print your design on large clear mailing lables and then seal with another unprinted lable on top?
