It does not matter which direction the InvisiLock sheeting is applied when used with MagnaMedia graphics. We recommend applying tiles and/or sheeting so that the VM logos are facing out (showing) and all of the material is applied in the same direction (all logos facing up and/or going in the same direction). If using InvisiLock magnetic sheeting to mount fixtures to the graphic wall then the direction is important and the section on Fixturing with InvisiLock should be referenced in our Tips and Tricks to a Trouble-Free Installation.
