Does anyone know if there is a company that can custom make a rain fly? I have an old Moss Little Dipper that seems sound but I would like to have a new fly just in case. I have the original that could be a pattern. Thanks in advance!!

Here's the link to Cooke Custom Sewing. CCS makes the best tarps anywhere and we own two different "regular" sized tarps. We also purchased a custom-sized tarp many years ago to mainly be used as a windbreak and we love it. Available in two different weights. Check 'em out.

Here's another option: Bear Paw Wilderness Designs

I made a rain fly, was a fun little winter project. And as a total amateur it turned out pretty great. It held up in some pretty big storms this year as well lol so still going strong. Always an option...
