Home made vacuforming

I have been brainstorming on how I am good to make my new food containers for social design problem 2. I don't think the oohmoo mold is going to work. I am looking for a crisper look than I think I can get with that. I found a great site on a DIY vacuform with pictures, models, details etc. Just wanted to share.
