Dont sew a hem you run oit of extra skriting some times.. I would attach tarp eyes the kind you use a hammer and die to put in on a anvil .. but would place towards outter edge like at 4 inch from edge and two grommets next to each other.. so you can pass zip ties threw to lash down chain.. then use zip ties to attach it.. I liked thicker Zip ties ..I spaced mine accordingly so it was evenly spaced and would hold skirt down on top of skirt.. I learned not to hem on mine.. so just passing along advice..
