Nicely done, and I love the illustration! What is your technique (you mention doing it in layers) -- and where do you get 3/4 inch square glass tiles?!?!
First I adhere the image to the tile with Diamond Glaze. Let it dry.
Then I coat the back of the image with Diamond Glaze again. Let it dry.
Third, I add a backing on top of the image, like a pretty scrapbook paper or something. I also coat that with a layer of Diamond Glaze and let dry.
Final stage is adhering the bail with E-6000 which stinks but works. Let that dry fully.
Then I strung it on some brown cord, attached a lobster clap clasp and Voila!
As for the glass tiles themselves...I got an awesome supply package of everything I need to make glass tile pendants in various sizes in a previous round of OWS. (On-going wish swap) I just know that my 3/4" hole punch fills the indented side perfectly on these.
Thanks! You can't see it but I finished the cord with a lobster claw clasp so it's more like a real necklace as well instead of just being tied.
I particularly like how the colors in the image carry out through the silver findings and the cord. Classy!
