226) Trim the screen along the top of the back end wall leaving about 4in. extra. Use a pair of large fabric scissors, a razor knife or (use a small electric soldering iron if the screen is woven, nylon based and subject to unraveling). Carefully cut the bug screen. Fig 222
227) Measure out 16 ft. of 84 in. wide bug screen flat on the ground and cross cut it. Use a pair of large fabric scissors, a razor knife or (use a small electric soldering iron if the screen is woven, nylon based and subject to unraveling). Carefully cut the bug screen. Fig. 223
228) Grab the bottom of one corner of the 16 ft. long by 84 in. wide screen, at 6 in. in from the outside edge of the screen. Position yourself under the screen. Hold the screen to the front end wall top girt at the right corner. Position the upper screen over top of the lower screen with the bottom edge of the upper screen flush to the bottom edge of the end wall top girt and attach it with a staple. Fig 224
229) At the front left corner, from under the screen, hold the bottom of the screen to the upper girt, over top of the lower screen and with the bottom edge of the screen flush to the bottom edge of the top girt. Leave enough slack so that the screen sags about 1ft. at the center and attach with a staple. Fig225
230) At the off center of the front wall at the right side of the door frame, from under the screen, pull the bottom of the screen straight up and staple it to the top girt while holding the bottom edge of the screen flush to the bottom edge of the top girt. Repeat at the left side of the door frame. Fig 226

238) Staple the screen to the top of the end wall cap and along the outside of the door frame at every 4 inches. Fig 234
239) Trim the screen along the top of the end wall leaving 4in. minimum extra. Trim the screen at the door frame, tight to the frame. Use a pair of large fabric scissors, a razor knife or (use a small electric soldering iron if the screen is woven, nylon based and subject to unraveling). Carefully cut the bug screen. Fig 235
Wall screen done and now it’s time for the poly film roof covering.
The wind must be calm when the poly film is set and fastened because the poly film has an extreme “sail” quality and it is very difficult to handle in any wind at all.
240) Unroll or unfold and place, top side up, a 22 ft. wide by 22 ft. long piece poly film roof covering on the ground along the right side wall. Do not step on it or snag it on anything. Fig 236
241) Bunch up the poly film about 16 in. along the edge, in the middle and at the ends, one at a time as you tie 3) 30 ft. ropes to the poly film, (3 raps each) and with a simple square knot oriented to the underside of the poly film, one in the middle and one at each end. Throw the other end of the ropes over the roof to the left side. Fig 237
242) Set 3) stakes into the ground evenly spaced along the left side, out away from the side wall as much as possible or out about 4 ft. Fig 238
243) Pull each rope one at a time until the leading edge of the poly film is raised about 4ft off the ground, and temporarily tie each rope to the corresponding stake as you proceed. Fig 239
244) Un-tie the first rope from the stake and pull more (about 2 ft. increments), and then re-tie it, repeat at the other 2 ropes. On the other side, help the poly film unfold if need be. Fig 240
245) From the inside, underneath, and with a step ladder, help the poly film, gently by hand as it is pulled over the top, pull each rope a little, tie it to the stake, then from the inside help the poly film over the roof frame, over and over and don’t let the poly film snag or get jammed up on the roof frame. Fig 241
246) Repeat step 244) and 245) until the poly film can be reached by hand from the left side, and pull the poly film roof covering over until it is relatively evenly up on top. Fig 242
247) Un tie the ropes from the poly film and the stakes and remove the stakes. Adjust the poly film at the top centers at each end and at all four corners and along the side walls, until the poly film roof covering is evenly laying on the roof frame. There should be an even amount of extra poly film beyond the ends and sides all the way around. Fig 243
248) At the front end wall, mark a 6 in. line at the front top center of the poly film where it folds over the top outside edge of the end wall cap. Attach a 6 in. peace of duct tape to the poly film just below the marked line. Fig 244
249) Pull ever so slightly down at the center of the poly film and staple at the center of the duct tape to the outside edge of the end wall cap. Pull slightly down 3 in. to the right and staple the right side of the duct tape to the leading edge of the end wall cap. Pull slightly down 3 in. to the left and staple the left side of the duct tape to the leading edge of the end wall cap. Fig 245
250) At the back end wall top center, pull the poly film with one hand, straight back and then down over the arch cap, keep tension on it, with the other hand make a 6 in. mark where the center of the poly film bends over the outside corner edge of the end wall cap. Fig 246
