tlc419 - Homemade Cards, Rubber Stamp Art, & Paper Crafts - Splitcoaststampers.com
That should work for the TLC gallery, but because Judy can't take pictures (eek, so sorry about that!!) there are no cards in it yet.
The gallery to upload to isn't specifically for Puzzle Piece, it's the general Embossing Resist gallery in Technique Spotlight
I'm so looking forward to trying this - need to lie down and try to kill a headache first though
