Some notes on technique
Simple adaptive/additional procedures, "not-rocket-science" ....and covered many times on the glassboards....neatly done to achieve the details Cathy put into her digital-photo-based GLasseye design....plus excellent colour selection. I suspect there may be even more plating to modify colours that isn't immediately apparent here.....I've only seen occasional "work-in-progress" e-mails attachments as Cathy has carefully and lovingly developed this piece.
