These little vases have thin wires around the neck, which extend up into a loop for hanging. They are so light weight, I just put a push pin tack into the wood on the side of the cupboards to hang them from. I'd love to have a garden window, but the estimate was waaaaay more than I was willing to pay, so this at least gives me some "garden" around my sink area.
This is what they look like when I'm out of roses, although there are usually flowers of some kind around here, but I like the roses best. I also have a lavender bush that's pretty prolific, and sometimes I'll cut two tiny bunches and add those.
See how much nicer it looks with the flowers? Colorful and warm. And pretty and fragrant.
