Pop up blinds are ok, a few feet of burlap works too if you have a decent back round. They won't care if there is something new, as long as it doesn't move.
I usually set up a couple of hen decoys, get in behind some mixed natural/man made concealment, usually with a big tree or rock behind me. Keep the shot gun or bow in pretty much the ready position and then keep my hands low to use the striker call.
