First you need a 14.5 oz can; washed and dried.
I file down any inside sharp edges with a file from hubby's tool box.
Click on the image to enlarge it and either save it to your computer or print it right from the preview. I use card stock but you can use regular paper.
Cut it out.
Grab a glue stick or a bottle of glue and smear the back side of the paper.
Line it up with the edges of the can and hand press around until it sticks.
Hint: I stand my can upright, hold the paper against the flat surface the can sits on and hand-wrap around the can.
Your kids may need some help with that. You too for that matter.
