I just read the thread start to finish. Great job! About your sewing skills - you seem to be a perfectionist so do what you want, but the seats look fantastic. Most of us resort to throwing some store bought junk that obviously was never intended to go in the boat we have. You have color matched comfort that clearly was made to fit. If my family were climbing into that boat, they would all be in awe. My iboats trained eye might be able to tell you made the cushions (only maybe), but only pure envy would be the result.
Some other notes:
quick postings seem to be on again, off again. I posted one question and got 5 answers that day. Next question took a week - but great info. If it took WOG a few days for the congrats, you know it was not for lack of caring.
Your documentation - list materials with cost, pictures to show why decisions were made, etc. - are a great help to those of us not yet into our projects.
And the result: it looks like a new boat. The color scheme was more than most would try, but well worth the effort. Way back when you were not sure if you would replace the transom, I thought this would be a so-so project. You took it well above the top-notch bar. Your fiberglass inside was good, the hull was inspirational and the interior finish is where it goes over the top.
Kind of a gushy post I know, but this may kick start my stalled project. Thanks for the post and good sailing.
