I had several sizes of candle pans in different finishes--some are the plain tin color, some painted white, and some rusty. I punched holes in each of the pans and just layered them together to make them look like flowers, and secured them with brads. I added some rusty wire to create the stems--although the wire wasn't heavy enough for the larger flower and it kept falling over. So I reinforced that one so it would stay vertical. :) The smallest shape on the small flower is a tart mold, and the smallest shape on the larger flower is a bottle cap.
In a way these are kind of Altered Art, since I altered the the pans to make them. Maybe it's a sort of way to upcycle too. But not matter what it is, I had fun making my Yard Art Flowers.
