I make each blue feather from fused scrap glass. This particular one features silver dichroic glass sprinkled into the top and then the glass transitions into a mottled cornflower blue. Transparent 3-dimensional glass is always tough to photograph well, but if you like it in the photo, truly, it looks even neater in person.
Please don’t use a suction cup to hang suncatchers of any sort in your window; they will detach when the weather changes and then the suncatcher will hit the ground. A ribbon over the curtain rod or a small hook in the window header will work much better.
