A LONG time ago, I saw this idea on Pinterest from BHG (couldn't find it on their website anymore) for a storage unit using empty cans.
I really wanted to make one myself.
So I started collecting cans.
Luckily I have a super nifty can opener that makes a clean cut without any sharp edges (it even allows you to put the lid back on if you don't use everything in the can to pop in the fridge!).
I spray painted the cans an olive green color to match my craft room.
Then I simply hot glued the cans together in a pattern I liked.
I had to really coat on the glue though. Maybe a stronger glue would be better.
You have to think about strength too. You don't want them too spread out where they fall apart being heavier on the ends.
I attached hangers on the back and hung it up! You could also just set it on the table or whatever too. Imagine if you made a huge standing shelf of this!
I filled it with things like pens, crochet hooks, paint brushes, glue sticks, etc.
Really simple to make and a great way to organize things!
