While researching stuff for Father's Day I found this amazing blog post:
Score!!! I needed a new can opener anyway :)
The basic gist is you open a pop top can opener with a safety can opener give it a quick rinse, and then fill it up with presents, and put the "lid" back on. With the safety can opener it just pops back on. You don't even have to glue it.
Then you decorate it- this is some recycled clip art I printed out. Or you could leave the original label on, and let the recipient think you got them a can of peaches when you really got them a diamond ring, the keys to a new car- or some Legos.
This is what I came up with
I filled it with his favorite licorice, and he loved it!
A regular can label is 4-1/4 inches tall, and about 10 inches around. The usable "front" space is about 3-1/2 inches wide.
A 20-oz pineapple can is about the biggest you can go if you're using 8-1/2 x 11" paper.
