I could not answer your questions about hexies, but appreciate that you asked them because they brought up a wealth of information. Hexies I could do, but multiple pieces in a PP block is something that ties my brain cells in knots, trying to vizualize the other side. I followed the link provided by Thimblebug and was impressed enough to go looking for the book on the top right side of that page. I now have the book on order from the library, and may end up buying a copy.
