Glass Christmas Decoration by Pamela
Glass Christmas Decoration by Pamela
 
I bought this in a shop in Cambridge England. All I know is that it was made by Pamela. It is 4.5 cm high.
 
It has a piece of foil sandwiched inside on which a pattern has been drawn. I think it is probably quite a tricky technique to get right. Wires have been inserted whilst the glass was hot, so that it can be hung up.
