I know it looks like a leaf, but I was thinking feather when I was constructing it. I think felt, with its lack of grain and structure, is harder to make a feather from than something that is woven and can be unravelled in interesting and effective ways. But I could be wrong.
The base for this is unsupported felt – I just started running the machine through some mixed layers of green until it started to solidify into actual fabric. I didn't stitch cobbling into the background, and I think maybe I should the next time. It adds coherence to the background, and is an opportunity for additional color and texture.
