It's real easy to work. Just scribe and snap like you would for model making. Admittedly 4'x8' sheets are a tad unwieldy, but we prevail.
No fasteners are required. I use a panel adhesive, No More Nails, it grabs well and drys fairly quickly.
Seams are dealt with by scabbing a splice plate on the back and gluing using solvent cement. In this case good ole Testors.
I'll use spot putty to fill the seams and it'll get painted in a couple of days.
I put up 40' of backdrop in a couple of hours, without assistance.
It's starting to look like a model railroad down here.
