Hello Making Friends
I am making a footprint for a tent from tyvek: should I hem the exterior so that the fabric folds over from the top side and is sewn (or taped) to the underside? What about adding gromets?
I am thinking that the hem would keep ground water from seeping between the tent and foot print if it were to rain.
I am also thinking this is too much work for very little benefit, and an unfinished edge is simple, easier, and just as durable (this is freaking House wrap).
Thoughts?
Grommets make sense since you'll be staking it, but yeah I'd skip the hem.
Maybe reinforce the corners with some triangles and make It 2 or 3x thick before you put a grommet through them.
I would agree you're probably overthinking it, but a folded hem might be a stronger attachment point for your straps that go out from underneath your tent to link up with your tent poles. I'd put grommets in webbing and attach the webbing to the Tyvek, but I am far from an expert...that's just copying the design of my REI tent and footprint combo.
