If you only used 1 bag for the side, you can fold the bag down so it's flat while you're sewing the bottom on. It's much easier to sew, though, if you put all 4 of the sides on the bottom, and then sew the sides together. Heres a pic of how to fold it down though. Mine looks like crap because it's falling apart and I need to make a new one. 




I got picture happy. Heh.
