I've been dabbling in PMC for a year and quite seriously for the past six months.
Everything I've learned has been through trial and error and reading a lot of books!
Here is a pendant I'm pretty happy with.
It's PMC3, the chain I made with fine silver wire (18 gauge jump rings and hammered wire). The stamps I used for the text and the seashell are from a collection I got at Alpha Stamps called
Under the Sea Cling Stamp Set.
The pendant is about 2.5 inches long including the seashell and the chain is 28 inches.
I plan on many more pieces! PMC is a lot of fun to work with and you don't have to be an expert to make something thoroughly satisfying.
