I just ordered 20 yards of silnylon. I received it last week. Look at the Jones Tent 2 on the homemade gear web site. He tells where two order it. All I could find around here at fabric stores was ripstop. Cost online was 3.00 a yard. Plus 5 buck cut fee per color and shipping. Name Of the place is Noah Lamport. You could most likley just Google NoahLamport They were much cheaper than even regular ripstop at the local fabric stores!
