I'm making an 11 foot gathered end hammock with the stretch side mod. What a great idea that mod is. I've searched and read a bunch of posts about how to do the mod but I can't find one detail I need. Here's my question. Measuring from the knot end where do you start and stop the bungee channel? All the pictures I've looked at seem to start a few feet from the gathered end "knot" but I can't find a specific dimension in any of the posts. What have others done or what do the commercial guys do? Note: I'm getting help with the sewing so it isn't practical for me to try it out and see what works best for me. Thanks!
