You could use double stick tape
Use a spray adhesive! Works well!
I don't know what canvas plastic is. You can glue and lay something heavy on it covering completely over nite to dry.
Locktite Supper 77 Spray adhesive. Spray both the canvas and foam board for a permanent bond. For a removable bond just spray the foam board.
Spray adhesive works great
i use my rolling pin. I first place my rolling pin on the edge of the material. I make sure that I roll against the way it has been rolled. when done I place several rubber-bands the material on the rolling pin and let it set over night. The next day I lay the edge of the material at the edge of my board place a few pins in the edge and begin to slowly unroll the material off the rolling pin as I cover the foam or canvas. You may want to place straight pins along the edge until you are finished and ready to secure the material.
Spray mount will do the trick.
3M makes a spray adhesive for foam.
Fabric spray should work for you.
I MEANT TO SAY FABRIC GLUE SPRAY.
