that stool looks fun to make and realllllllly uncomfortable to sit on for any length of time. . .
I use a "Crazy Creek Chair". . .here's REI's less expensive version of one:http://www.rei.com/product/783805/rei-trail-chair
they also have this, but it costs more and weighs more:http://www.rei.com/product/812535/lafum ... ding-chair
I carry my Crazy Creek chair around with all over the festival, use it at stages, meals, workshops, hanging out and chatting with friends. .. I got a piece of coated nylon to use as a ground cloth under it, and carry that with it to protect myself from dirt and/or wetness. . .
and I keep it in my car at home for impromptu picnics or group gatherings where there is limited seating or uncomfortable seating.
You can always get a low chair at the Cuntree Store.
Or, check the "borrow/loan" thread. . .some womyn are bringing chairs for others to use. . .perhaps you coud works something out.
