I received a copy of Lloyd Kahn's Tiny Homes: Simple Shelter: Scaling Back in the 21st Century for Christmas, and have been studying it closely ever since. He is an old surfer hippie, and has a number of shelter books, going way back, that I haven't read. In this book, hundreds of pictures show tiny homes of all kinds, from boats to converted horse trailers to hippie vans to hobbit houses to treehouses, where the builders were constrained by resources more than by building codes.
Building under those conditions is a lot of fun. But I am not in a place in my life where I want to build a tiny home for myself.
However, I had the twigs that I had saved from the Christmas tree, and some bits of bark that a tree in the back yard had shed, and some twine, and a glue gun...so I made an elf house. Apologies for the low-quality picture, but there is an elf chair on a small deck of twigs, and a bark shelf with an acorn bowl of pine needles. There is also a high, round perch. I built it up a little at a time on a cookie sheet, with pauses to let the hot glue solidify (I use the high-temperature-melt glue). I wrapped twine around the more visible glue joints. It was a lot of fun to "build", and I only burned myself once.
