I bought some fleaz to use on my tarp and they kept slipping. I'm not sure if I'm doing something wrong. I have 1.75 lash it on each end with a Ti Dutch hook to clip around tree. Then I have my fleaz on a continuous loop on the D-ring of tarp. I bring the line from the tree to the fleaz and wrap it up per directions(I have wasps and tarp flyz so I know how they work). When I went to the other end to pull it up tight, the side I just hooked up would slip from under the wing, the only way it wouldn't slip was if I put a half hitch in it. Which isn't a big deal but my wasps and flyz didn't do this! Am I doing something wrong? I was doing this this past weekend and I didn't get pictures but thought I would ask the question.
