Making arrangements in tin cans has become one of my favorite things. It's a nice way to recycle, and makes an easy gift of your garden flowers. I make weekly arrangements for my son's preschool class. Using tomato cans is economical, recyclable, and non-breakable if they get knocked over in the classroom. I save the cans that come though my kitchen, I love tomato cans, with or without the label, vintage or new. I also keep my eye out for them (water tight is a must though) at garage sales and thrift stores.
Some more tin can arrangements from last summer. I favored the cans sans label. They look great on a kitchen table, or if you're dining al fresco, you don't have to worry about bringing them back inside or the wind blowing them over and breaking a favorite vase.
