Well, I assembled a thing at least, an 8โ€™x10โ€™ vinyl shed. I went with a prefab job like this, because I hope to be able to add a stall onto my garage someday, so I wanted a shed that I could move.

It went together pretty well, a few hiccups. I did most of it myself, but thankfully a neighbor came over and offered to help when it was time to put the roof panels on (that really would have sucked by myself). All told it took 5-1/2 hours.
