wenchie...un-flippin-believable!! I think you are so talented and love ALL your creations you showed us!! This is just amazing!
I also love to do 3-D stuff so NO, you definitely arent the only one. Unfortunately, I have been creating cards and stuff for a couple of craft fairs a friend and I do in the fall and so my stuff has been much simpler. You cant sell any of the elaborate stuff at those...no one sees the value. =(
Here is a haunted house I made that holds mini cards and tags inside...
Southpaw Paper Arts: Spooky Haunted House
Heres a link to the blog post showing the top opened up and the cards inside too.
Here is a pic of it....
