Orly Fuchs Galchen pursues hollow polymer forms and she’s come up with light, bright empty hearts. Her Facebook and Flickr pages and her Etsy shop are filled with examples in many styles including these wrapped with lovely bands of graduated color.
Orly swears that she only uses polymer. No filling with sugar, salt, paper, cotton or foil. No making two halves and gluing. No double baking. You have to buy her tutorial to learn her secret or be resigned to a heavy heart. (I couldn’t resist the pun.)
