Our Arches (leapers) were made using the method outlined in the DIYC WIKI. I think the method works great. No 10 or 12 foot arches to store away. Each arch breaks down into 4 sections and is easily store in the attic. They are approximately 12 feet long and have 8 Channels on them. Two Channels on each section. They are installed so they are approximately 7 feet wide and 4 ft high. The pictures below, show the tools and process of making them. Drop a Note in the Guest book if you have any questions.
