@shirlz,
Hi Shirlz,
Don't worry...I almost wore out the eraser on my pencil, too. But I found it a lot of fun. It's funny - it reminds me a little of the Skeleton puzzle, yet I can NEVER solve that one! I despise the Skeleton so much that I refuse to even attempt it anymore.
Dutchy, I knew you'd get it. Ye of little faith
