My girl child wants to down grad from a full size bed to a twin size... Presumable to make more room for shoes and clothes on the floor.

Seeing as my husband, Angus, now has a shop bot, I approached him about making her a twin platform bed. Something minimal and simple. He laughed at me and said there is more to making a bed than nailing some legs on a piece of pine board, then suggested I come here to educate myself.

So... How hard is it to make a twin platform bed? What kind of wood would you use? How long is the process for the inexperienced? Apparently I'm on my own in this project, lol.

Help!
