Robin Betterly's Secret Books

I found these Secret Book kits by Robin Betterly a while ago. The outside looks like a tiny book, but inside are two secret rooms. They are so neat and well made. The instructions are easy to follow (it was my own fault that I put the book together backwards).  This one is called Castle Spells; the top room is a bedroom, and the bottom room is an office (where all the spells are kept).  The scale is approximately 1:144 - so this is tiny!  I really enjoyed putting this together and wish I could get some more (so that I can put them together right this time and show that I am NOT an idiot :)
