Whether you believe in Fairies or not, this is a fun project nonetheless.
To build the actual house, we used twigs from our willow and lots of glue, some nails and, YES, zip ties. Everybody had fun pitching in, even the 10 year old.
We then put the house in a shaded spot in our back yard and the girls went crazy decorating it.
And wouldn't you know it?! This morning they found a half eaten raspberry on the table.... ;-)
Even if no fairies or gnomes show up, it still makes a nice outside play house for small dolls.
