I'm in love with this mobile. (Seriously.) Because it's copper, it's not only beautiful, but it can be used indoors and outdoors. Its maker, Rachel, chose to put her's outdoors and left it unsealed so it develops a natural patina over time. (Yes to patina!) The materials to make one are minimal and include 1/8" copper tubing, florist wire, clear fishing line or microfilament and the very optional clear spray sealer.
