One of the groups I am in has just completed a fairy door challenge - I didn't have a chance to go in it but love the fairy door idea - I want to add one to my shop at some stage! I love this website http://www.urban-fairies.com/ it showcases the fairy doors of Ann Arbor.
I also love this site http://www.fairyhouses.com/ they have a book called Fairy Houses Everywhere which my friend's daughter, Annabelle, just loves to look at every time she's in the shop. I also love these escutcheon's that are made by 7Gypsies - have a look at the photo at left. Isn't it great?
