Matt, You are truly an intrepid Buick restorer! I have recently completed the reupholstery of our 49 Super and it was a fascinating experience. Like you, I started out by carefully removing the material for patterns. I was successful with that. I was going to sew up the new upholstery with the help of my wife who is excellent with sewing and fabrics. She took one look and told me I was nuts. So, I bought a kit that was already cut and sewn but I will tell you that we had some great fun doing the work. A good heavy duty old sewing machine like a Pfaff 120 will be your best friend. And forget the tacks (in most places). They were skilled artisans in the '40s and used tacks skillfully but today, a good upholstery staple gun and lots of hog rings will be your next best friends. We just finished the work on the front seat which took us the longest of all the pieces. I've attached a couple of photos. Keep up the good work. Dan
