Hi,
I waited for a windless day to put my plastic on. I have a galvanized pipe hoop frame to which I have a 2X8 baseboard fastened at the bottom. My height was a little over 7 ft. so I allowed about 8-1/2 ft. to go over one end plus the 32 foot length and another 8-1/2 ft. for the other end. This was about 49 ft. that I cut from my roll. I put my plastic on the driveway and laid the plastic out with one edge loose from the folds. I took 4 pieces of 1x3 and laid them end to end in the center of the sheets edge and with some help (3 others) we rolled the plastic and wood together about 4 wraps and proceded to staple gun the plastic to the wood. We then carried the plastic to the side of the greenhouse and laid it along side. The next step was to pull the plastic over the hoops and go back around raise the plastic over board side to the base boards and nail it on. Back to the other side where we pulled the plastic straight and trimmed the edge back to where we thought we could get about 4-5 wraps of plastic on the 4, 8 ft. boards on this side. We used the same procedure to wrap and nail down this side. On the enclosed end I did a fanned pleat and staple job to so that it looked like a fan when I was finished. The other end I fanned , stapled to the frame and trimmed the rest off. Just pulled the plastic taut, not tight when nailed to the base board. Good luck
