How cute!! It's so tough to decide because they are all so great, but I think that #1 gets my vote :-) Thanks for sharing!
I like the simplicity of #3. :)
Those look like they were SO much fun to make. So, which one do I vote for? Hmmmm... I think I'm going to have to choose (and it's avery close vote here) - number 1. Congratulations to each one who made a house.
