Brooch backs are really not that expensive, I go to a funny little fabric and craft shop in a small local town, and she tends to have something you want any time you go in. So a dozen brooch backs are not too costly, and judicious use of a hot glue gun ( would this work for the frame purse? Possibly not, as the glue goes off too quickly), and you have a brooch.
I can see myself making more of these, and various other variations come to mind!
This brooch pin is secured with a fabric band stitched to backing, and then glued to stop it slipping- hot glue guns are wonderful-
And it sits up proud, a bit like a real butterfly!
The other one I glued directly onto the butterfly, so this feels less secure to me. I don't think it really is less secure, but feels it!
I think this is the better version to go on this bag, I am sure I will find another home for the other one!The back of this has the pin attached with some fabric. I think this is because some of the colours in the lower wing echo the bag fabric.
