When I first started playing Mario Kart way back when, I got to know Bullet Bill rather well. In fact, he was my best bud! I only say that because I usually needed help catching up to the rear of the field because I had already fallen off the course too many times to count.
For this one, I ran the design through the “Stitch Editor” module in 5D Professional. Originally, it was about 6,000 stitches, but optimizing the design removed about 2,000 stitches! All these extra stitches were with the triple-run blanket stitch; the machine would stitch about 3 times in the same hole before moving on to the next leg. With those extra stitches gone, this design was speedy, just like Bullet Bill!
