Cheers John, I appreciate the good words. I have considered doing the coloured piping as you suggest, and I think it could work well, especially on black seats. I haven't tried it yet, but I think it's worth a shot. I have also thought about painting the seats in the piping colour using one type of paint (say, acrylic), then painting the seat in another type of paint (perhaps enamel), then using a small, pointed swab dampened with thinner to remove just the paint from the piping, to expose the colour underneath. The trick is finding a thinner that will cleanly remove one type of paint without effecting the other. Some experimentation is in order.
