Straight to the point:

Do you guys(and girls) no of any plans to make a bjj/judo mat
or any ideas things you've tried in the past- obviously i would like it to be cheaper then actually going out and buying mats.

i want it to train at my/friends house so its for a relatively small area(i couldn't give u a number though), its has to be atleast the thickness of say, the average akido mat though(thats what i train on normally).

BTW: how would grass hold up training bjj/judo?
