Excellent work, Booger!

Just tell me, how do you stop the fabric from slipping under the foot of the sewing machine? I have an old cheap sewing machine, too, but for ordinary fabrics, not heavy duty stuff. I've tried sewing lycra before, and a slippery plastic fabric that I had great trouble feeding through the foot because of its slick surface.

I have to say that my days of using double-walled tents might be numbered. I frankly don't see the point in carrying around what effectively are two tents to make one. The condensation issue is one that might be tricky in cool weather, but the inner of a double wall tent often doesn't stop the occupants from pressing up against the damp outer wall anyway. And when Machka's bike was stolen from right next to our tent, the opportunity to apprehend the culprit was hindered by having to get through two zippers first.
