It's just changing up the angle of the fill stitches (direction that they are stitched in) that adds extra dimensionality without having to do other things like blending (which also depending heavily on stitch angles) etc, to achieve that same effect.
Evan, the overall stitch count on the car alone was about 39,000 stitches. I am not at the shop right now, so that is just going by memory, which isn't always so accurate!
Oh, I should also mention that the embroidery shown here was done on 3 layers of pellon or backing. I had no thread-breaks, birds nests, no mechanical issues whatsoever with first sew-out. Yay! Usually I have at least one change after my initial sew out. This thing went flawlessly. I picked over it quite a bit before test sew out. One problem I saw in test sew-out was that my gray outline around the entire car got a little too far away fom the gray fill of the windshield. I only use outlines like this if I need to to define an edge like black embroidery thread against a black jacket. So, there is a little gap between the front windshield and the gray outline. But that did not happen on the actual jackets. I had my backing a bit loose in the hoop when I loaded it, and then as the design was building during the sew-out, it began to pull the design in the fill part of the windshield. That will make sense to some of you and no sense to others. Thought I'd explain though, just in case you noticed that! We are our own worst critics. But rest assured, it was not an issue on the Customer's jackets.
Thank you EVERYONE for the nice words! Evan, you are such a great communicator! Yes, there is so much more to embroidery than meets the eye. This is just part of my design, the lettering part of it was full of "OOh and Ahhh" responses from my Customer. But I did not include that, just to respect his privacy. He has me putting his Company name very old school looking (I custom designed his lettering!) big across the back of the jacket. The car in the center is something he's paying for separate when he or his family members or clients want their own car featured in the center of the design.
So really, the custom car part is just the second phase of this design and I must admit, the part I have worked the hardest on. As said, I do enjoy this type of painful work. LOL!
I agree to all Evan said, he is just a much better speaker and writer than I am. Thank you Evan!
Hopefully you enjoyed seeing the photo I worked from, I hope it helps explain some of the process anyhow! The next car I did for this Customer, which is a Model A Ford. The Model A Ford (picture coming soon) was a 45,000 stitch design, for the car alone. Lettering with Customer's business name above and below was additional stitches, I think about 13,000 more. Add that to the truck, and total was about 58,000 stitches.
