Pole pockets are created by wrapping 4 inches of mirrored image material around the sides, top, or bottom of the banner. The vinyl material is folded over the backside, similar to hems, but with space for a pole or rod to slide through the pocket. This material is heat-welded to the backside, forming a smooth 3-inch seam. It's important to understand that the pole pockets are included within the selected banner dimensions and do not add extra size. For instance, if you order a 10x8 feet banner, the total size, including the pockets, will be 10x8 feet.
