I got a price on re-doing the interior on my Catalina 30, and nearly went into cardiac arrest!!!! I calculated the cost of doing it myself & it came out to a savings of 77%, assuming that my time is worthless - which is not far from the truth! Either of our home sewing machines will handle Sunbrella or equiv with a heavy needle. My limited experience says that if you have never done it, keeping a long seam straight is not as easy as it looks. Especially if there is welting or a zipper involved. I'm also thinking about investing $50 in a sheet of 3/4" plywood and formica to use as a layout table. I think it would make layout and foam handling so much easier.
