I absolutely LOVE dollhouse miniatures, I don't do a lot with them, but I've been toying for a while about doing something How I Met Your Mother related.
Right now I have a little mini-salute to Barney and Robin in one of my bookcase shelves. It's nothing elaborate just a couple things that bring the characters to mind.
Eventually I would like to add a yellow umbrella (if I can figure out how to make a tiny one that looks realistic enough.) I really wanted to have symbols for all 5 characters but I had such limited space that B&R won out (duh)
Pic here, if anyone is interested...
