If you don't mind ordering out of state, try Dave at King Marine in Seattle. King Marine supplies quite a bit of canvas for C-Dory's and has patterns for all of the boats in their shop. Dave's number is 206-271-2294. Just brace yourself for the cost of a custom cover versus a mass market cover.
By the way, Our 98' 22' Cruiser has King Marine canvas on it and Dave just installed window covers for us on Friday. I'm also going to have him make a mooring cover and some cushions to convert the dinette to a settee based on how other C-Brats have done it.
