Wonder if anyone can point me in the right direction, please? I'm looking at ways of transferring children's doodles onto keyrings and pendants. I went down the route of silver clay (fingerprints etc) but I didn't enjoy doing that and it's very, very expensive. What I want to do is take a doodle, shrink it in size and put that exact doodle (with colour etc) onto a keyring or pendant blank. I've seen some on the internet and they seem to have a clear plastic coating over them. Does anyone know what this coating is? Can anyone point me in the right direction for instructions on how to do this process?

Many thanks!
