This is a stained glass suncatcher made using the Tiffany copper foil technique.
It is a butterfly made from pearl coloured glass, iridised with a lovely shimmer, opal being the UK birthstone colour for October. The other sections of the butterfly are clear, iridescent glass to give it even more shne.
I've made the little glass pearl coloured head in my hotpot kiln and added tiny dichroic chips for a face.
