I'm in the process of setting up a twin lance 25' seamless orange track for the Cub Scouts. I tried using Velcro and it seams to cause a valley between the Velcroed sections. What is the best size Velcro to use? I stuck one part of the Velcro the the track and the other to the wood frame. Also, the track is resting on 2x4's with 1/4 inch shoulders to keep the tracks centered. Is the a better way other than using rubber bands to hold the sections together? Thanks in advance for any help.
