Hi Earthan! A good way to present your paper on Cob would be to build a model. We have been doing that and having a blast. You can make it as elaborate as you want and it is very easy. I am sure many paople will help you with ideas. One thing...when mixing cob for models, cut your straw up into smaller pieces. It is hard to mix it well on a small scale when the straw is left at it's normal length. Glenna
