One of my 45's that will be there i did the seats in a tan sunbrella. And we call it fabric welding, not sewing. Always keeping my eyes open for a toyoda machine. This was a quick just get the door functional thing. I have quick hinges and they are in a different location than stock so moved the pins on an old set of besttop doors. I am donating a set of mcdesign quick hinges to the raffle and you can see how they work on the tan 45.Are you doing your own sewing? That's impressive. You and my wife should chat she's spent her career in clothing manufacturing and production.
