How can I keep a big poster in PVC pipe?

Answer 1

Roll it up and stick it in the pipe.

Answer 2

Like scottr says, but buy a couple of pipe caps. They have some that glue on permanently. And some that have a fitting you glue on and the cap can be twisted on and off for access. You might get one of each. The pipes come in lots of sizes, 3 - 4 Inch should be about right. Go to the home center tell them what you want to do, they'll help. I think when you actually see the parts you'll get some ideas. Hope this helps. Charley
