Remember that anatomical heart necklace I was waxing all "I want this" about a few days ago? Well, after studying the pictures (and engaging Sweet Husband the Jeweler in studying the pictures) I determined a close replica of such necklace could be made with a shrinky dink.
I happened to have some ink-jet printable shrinky dink material around the house (from a failed experiment a few Christmases ago), so I found an anatomical heart drawing, printed it out, and shrunky-dunk it according to the package directions. Lo and behold, it worked! Yay!
Once the heart worked out, I went a little shrinky dink crazy. Even the dogs got some new jewelry--a nice little family portrait to wear close to their (figurative) hearts.
