Well I have got round to doing it and I can honestly say they look fabulous and are really easy to do.
I printed off some pictures of things I like, printed them to size(well near enough but you can't tell ) and stuck them on.
Yes it is as easy as that. You can do it with all different sizes of cans and decorate how ever you please.
Have a go, you won't be sorry and unlike some crafts you won't be thinking at the finished product
god I'll never get that 20 minutes of my life back!
