The Yard Master 2 screen material is folded so that it can fit into a smaller package to decrease freight cost. If you notice crease lines on the material upon opening the box, there are a couple of things that can be done to alleviate them. The easiest method would be to allow the material to stretch on the Yard Master 2 frame. Over time, the creases will alleviate to a minimal. If after a few days you do not see any improvement, the second method in alleviating them would be the use of a hairdryer. Set the dryer on medium heat and blow on the material from its back side from about 3 feet away, concentrating only on the crease lines. Do not apply excessive heat as this will cause for the material to deform. You may need to repeat this process for a couple of consecutive days depending on the severity of the creases.
