I love this idea - and I have a big bite that could easily do this. Tin Can Lanterns for table centerpieces. Cheap, recycled, and easy enough to make. Throw a little heat-proof spray paint and ribbons on them to add a little color.
I've been looking for some really cute string lights for our camper. I think I'll make these out of really small cans I have and poke dragonfly designs in them . I like the pastel colors! Yea, And it's not going to cost me a small fortune ! I love Pinterest !
