Background piece of butterfly: Rose gold mirror (solid backing shape)
Front piece of butterfly: Plywood (monarch design cut)
Text: background of text makes part of the plywood cut out above - text engraved so will show as a burnt wooden brown.
Overall size: 61x48cm (note the frames in the below draft are to the same measurements you gave, so this is how big the butterfly will look).
Note: Butterfly cut in half down the centre, so one half can be stuck on to each frame.
