I had prepared one of the mirrors ages ago by giving it a base coat of paint (which was as far as I got with it at the time!), so all I had to do was cover it with Botanica papers and add a few extra elements cut from the papers, which I attached with silicone glue to give them a bit of dimension.
The large butterfly and the bird were cut from the toppers which are part of the collection, and the small butterflies from the papers.
PS. Just realised this is also eligible for the Butterfly Challenge, so I've entered it!
Thanks for looking!
