I have had some experience with building straw bale infill walls. They are labor intensive and take a bit of skill, but the results are worth it.
The best advice I can give is to try and find a workshop near where you live. These are generally great hands on learning opportunities.
The other tidbit of advice is to check and make sure your local building ordinances will permit a straw bale wall systems. To get the proper permits, you sometimes have to educate the local building inspectors.
