I have finished the little houses. I found some fabulous little trees and battery multi coloured LED lights. I made little openings to fix 4 LEDs into each of the backs of the houses to hold them in place and mounted all of the houses onto a board. They fit really well on my photo shelf.
I think I will be making more of these... especially with the kids..!
Here is the website where I got these fabulous house templates
Thanks for looking.
