Well, I got my booklet on thatch roofs from UK and found to be filled with excellent information.
Also there is a good deal of information free to all on this site:
http://www.countryside.gov.uk/LAR/archive/publications/thatchers_craft.aspThey say you can use almost any type of straw or whatever looks like it. The free downloads are filled with very good pictures.
I will be ready to make a test soon. Will post my results.
I plan to cut some weeds from the swamp across the property to run the test.
