Does anyone know where I can get Closed Cell cushions for the catbird seats?
You're probably going to have to trace out the pattern you want then send it or drop by a canvas shop unless you can sew them yourself.
Most of the big marine canvas outfits would have patterns for cockpit cushions, but probably not the bird seats. Could be wrong..
Or maybe "mobile" canvas guy if you can find one can drop by your boat.
JSI on clearwater, FL does the work for Hutchins but there are hundreds of places that can sew you covers. Sailrite could probably make 'em too.
