I am looking for Model T embroidery designs, if anyone has any idea of a company that sells good quality accurate designs the help would be very appreciated.
This may help? If you have not tried already.
Use Google and put in Model T embroidery designs.
I found a few when I searched.
There is a book of line drawings that work very well for what you seek. The good news is that they are also free of any copyright limitations. That book is by DOVER Publications or something like that. I found a very nice Model T touring car in there that I was able to lift and use to make the graphic for the Byways MTFCI annual tour a few years ago. Children's coloring books also make a good source of line drawings if you can find one on the topic of old cars.
