Recover cushions - NO SEWING!!! I have sewn since I was age four (really!)- and I have never wanted to tackle cushions in a trailer/RV. There is no way I would be happy with the results. This is awesome!
Wriggly Tin Shepherd's Huts. The double doors really let the outside in and make the hut feel incredibly spacious. The hut is fully equipped for up to five people. http://tinyhouseblog.com/vardo/wriggly-tin-shepherds-huts/
