I asked this on Facebook, and only got one response.
Does anyone have a bag idea or storage bag for their various rudders? If so, where did you get it/how did you make it?
I made one in the past by sewing two towels together and then sewing that into sections for my weedless, surf and hybrid rudders. I just want to see if there is anything else out there before I do something like that again. I sold that with my prior surfski.
