She explained on her personal Facebook:
When this little guy presented himself to me with such a torn and damaged set of wings, I posted about it on my personal FB page. I was, needless to say, heartbroken at the thought of having to put him down. Then a friend sent me a video on repairing wings. I figured, since I do so much designing, cutting and putting together of costumes… I could give this a go. And I’m really glad I did!
