We are looking for a better solution for creating a backstop inside our clubhouse for use during our indoor 3D league. Currently we are using sheets of plywood with rubber belting attached to them. They are very heavy and hard to manuever. Does anyone have any user friendly ideas? How about some pictures of things that you guys have done? Here is a picture of the wall we cover up. The dimensions are 18 ft across with 8 1/2 foot ceilings. Thanks for any help.
