Now here comes the fun crafty part.......decorating!
Working in small sections, apply a thin coat of Mod Podge to the outside of the cardboard tube. Lay down a single piece of tissue paper in the glue, wrapping it around the tube. Use a small dab of mod podge to seal down the ends of the paper. Once you get the entire tube covered in tissue paper paper let it dry and then add a few coats of Mod Podge to seal it.
You can't get the tubes wet, but you can gently clean them with a slightly damp sponge or wet wipe. And don't leave them outside over night while you snooze away in your tent. Sitting out in moist air will ruin them (says the experienced Girl Scout leader). With proper care these upcycled DIY marshmallow roasters can last for years of roasting fun.
Cheers and happy crafting!
