I'm nervous about doing anything at all to it besides just letting it sit on the table. Not knowing what the mats at the tournaments will look like, and whether or not there will be time or space for anything to be done for them, I don't want to get there and have a different landscape than what we've been practicing on. I don't know, I'm torn!
Has anyone tried flattening the mat by putting it on the table and loading it with textbooks?
