i don't know, could you thread 1/2" grossgrain through there?. even so, might have to redo the hem at the corners (not that big of a deal), so the hems were open at the corners and so there was an inch+/- or so between the two sides (see diagram on previous page). also, make sure to get the amount of gg that sticks out of the tarp just right. too much sticking out and the hem openings could get stressed, to little and the corners will be a little wrinkly. just keep the same angle the webbing has coming out of the hem. it's not too hard if you watch for it. use a pin or whatever to hold it where you want it.
