Perhaps an angel with mylar to hang in the window, some will fit into the card without being glued.
I have looked at some but most are too big. I don't think they should be any more than one and a half inches high.
I can easily do a 90 for you, with or without a loop, in that size, but not this week. Next week would be possible.
