Eco Friendly Sod Roof Gnome Home

For a while now I have wanted to create some eco conscious toys, which help a child learn about being Earth friendly and promote that awareness as they grow up.  Playing with toys that promote a healthy , earth happy life is a great way to "to plant seeds for positive growth".   I came up with a sod roof house and will make a play mat to go with it. This house has a roll down door cover, a thick sleep mat,  flower boxes under the windows and little mail box with an opening lid.   I also am thinking of the best way to do a thatch roof out of felt. I have also made a bee skep to go with the Sod House, and a play mat with a vegetable  garden.  I need to make a rain barrel too!
