I actually just made a ledge for my first wall about a week ago. I looked at the Krusty ledge stuff, decided I didn't know how to sew, or want to learn, so I went to Walmart and bought the Ozark Trail Cot. Thought I could use some of the cot pieces, turns out I couldn't. So I just used the fabric, bought about 10$ worth of PVC pipe and fittings, used some old webbing for the connection points, and kayak hauling straps for my adjustable straps. Total Cost around $60.
