The correct color thread is natural color and that is a very light beige. The thread is not the upholstery color. I use 8 ounce spools of bonded polyester size 92 or size 138 if you like a more visible stitch. I like the size 92 with a right twist. I get my thread from the Thread Exchange in Weaverville, NC 1 800 915 2320. The prices are very good, the quality is great and they ship quickly. They also have preloaded bobbins of different sizes depending on your machine, but I wind my own bobbins. I have done my Darrin Interior and Top and carpets as well as my Frazer Manhattan. The natural color thread is correct for both vehicles.
