Didn't mention but this requires a starting clamp. For the short side you will need about 14' and for the long side about 24'. Run in the center 16 mains and use the short side to run in the fifth cross (you only have to weave through the first four mains.) Hold the short side with a starting clamp on the outside of the frame on that fifth cross. With the long side run in the fourth cross and clamp to fifth cross, and then the third. Now move the starting clamp to the eight main on the short side, or use a flying clamp to hold the eight main on the short side (easier.) remove the fifth cross and use the long side to run in all crosses except for the bottom cross and tie off. Use the short side to run in the outside mains and bottom cross, then the TOP cross and finishnup with the second cross and tie off.
I would like to apologize to anyone I have not offended. Please be patient I will get to you shortly.
