thank you very much
re the "Just one question...is that third picture of a pin? I LOVE IT! What kind of backing did you put on it- a pin or a magnet?"
yes it is a pin and it has an ordinary brooch back on it - one of those silver coloured ones thats about an inch long with 3 holes in the metal bar.
i fixed it on by laying two bits of thin wire across the back of the pin/brooch where i wanted to put the brooch pin on, i soldered the ends of the wires on to the edges of the back of the frame. then i "tinned" the wires and the brooch back separately (tinning is just covering with a thin layer of solder - flux first). then i laid the brooch back on top of the wires and just heated the untinned side with the soldering iron - this melted the tinning solder underneath the brooch back on to the tinned wires and it stayed on !!
by the way, in the UK you can get lead free solder from plumbers merchants - you have to use it for soldering pipes that carry drinking water
