Bed Frame

I noticed a few people with their beds framed. Can anyone post some pics of their framed bed, what size bar works best, and any tips before I start this tedious task?? Thanks.

1.5x.5 is my choice, flat, rigid, and light

I don't even know where to start, but I want to make sure I have enough support everywhere I'll need it. Beds pretty tore up and most of the inside is pretty useless, plus I'm wanting to sheetmetal the whole inside. So I'm looking for some advice on how to get it started and what to watch out for. Thanks for the metal size. That helps.

start with a big rectangle to hang the sides from.

3/4" .093 wall tube. I've had 4 people sitting on the bed, its plenty strong.
