Having trimmed off the overlong reed, I made and fixed down a tapered roll to create a fixing point for the ridge. Now to the sedge, move your hand in the wrong direction (on the edge of the sedge) and it cuts you badly. This needs arranging, evenly in both directions, over the ridge. My first attempt had to be completely removed. Thanks to my tutor's skill and patience we got it in position, managed to spar it down and trim the edge. All I had to do now was net the entire roof!
