I'm stuck in Afghanistan, but my Dad's emailed me the pics of his best finds this spring.
The smallest of the bunch is the first. They haven't been measured, but it's sitting on an 8.5x11 pad of paper. The squares on the linoleum are also approx. 8x8"
Interstingly he hasn't found any little antlers this year.
This doesn't really count as a shed, but it's cool none the less
