No Trespassing Vinyl Cheap Signs
These are the typical plastic signs that you can buy at Home Depot or Lowes or Ace Hardware stores. They can be tacked up pretty much anywhere.
To keep the in place for videos we use large glue dots. Those are the think clear bugger that comes on may mail products. That seems to work on most surfaces and can esily be removed and reused.
Of course we stock an ample supply of adhesives, tape and fasteners in case you need them during your production.
