My kids really enjoyed this project because the recycling was just picked up the other day and I need some empty cans, so they got to create a lunch using any cans they wanted too. They choose burritos, pineapples, and peas for lunch. Interesting, but doable. After lunch was completed I washed out the cans and got started.
Empty and Clean Tin Cans (or try Mason Jars)
First thing you need to do is measure the height and width of your cans. If you have a serger you will only need to add an inch to your height. If you do not have a serger you need to add 1.5 to 2 inches to your height. I also added 2 inches to my width so that I would get a nice gather to my fabric. Once you know your measurements cut out your material to match and cut out your elastic to the true width (not with the extra 2 inches).
Do this to both long-sides and then take your fabric back to your sewing machine and using a 1/4" seam allowance, stitch from one side to the other on both long-sides.
Now turn your fabric RIGHT-side out and slip it over the can.
