I was using my old throwline bag today(an orange trick or treat bag), and thinking how much it sucks. Not nearly as good as my makeup bag :^D It's good enough for my work climb system, but I was thinking of maybe making something better. It occurred to me a big round tarp might work pretty good. Cut a big circle out of a regular tarp, fold the edges over, and install grommets around the perimeter. Run paracord through the grommets, and it could be cinched up like a bag. When you're ready to work, pull it apart and lay it on the ground. Easy to flake line on, and when you're done, pull the cord to bring it all together. Sound like a good idea?
