I have one in the fridge that is waiting to be done with to try that out with. I want to save it for an especially long banner.
How sharp is the metal on those tubes when you cut them?
Fairly sharp, but the metal is soft so you can easily buff the edges with a little fine abrasive paper or an emery board to smooth them.
Done this with self printed flags on an inkjet printer as well. You just need to spray varnish the flags first to stop them bleeding colours.
Yeah, although I would spray both sides just to be sure the paper doesn't absorb enough moisture for the ink to bleed. (...perhaps that's what you do?).
Using something like canopy glue rather than cheap white PVA glue helps with these things as well, as there's less water in it.
I wonder, have you tried using spray mount?
The heavier foil from disposable baking trays is a decent weight for banners and what-not. I scuff it up on both sides with wet-&-dry paper before I paint or glue it; it seems to make them more resistant to handling.
This is a
great idea, and a fine alternative to the puree tube. Unlike normal foil that's way too thin, this thicker stuff keeps a nice shape.
