It is gorgeous and looks like it would blend in perfectly with your avatar. All of it is just so shimmery - - makes me wonder if it is all embroidery or are the surrounding blocks pieced with "shimmery" fabric?
Those surrounding blocks are what I really like. I don't recall ever seeing that particular block but it would be easy to replicate.
Opps - I see that you added a comment as I was writing mine. Are the 4 blocks courthouse steps (log cabin) blocks??? Similar maybe with a little modification???
