I've learned so much from lurking around this community, I thought I'd share what I've been working on recently - though they aren't fur, many fursuits that I've seen include these - wings!
Wow, great response - tutorial it is! Expect another post within the week~
NOTE: the arm-brace in these pics has been successfully replaced with a glove (yay circulation)
Wings weigh between 3-4 lbs currently, very easy to move in.
