The design was made in mind with a collared shirt as its finished product. I did not want the stripe to stand out but wanted a little something extra. This, in the end was not the design I used, but I liked it, and in turn made it for sale.
Did you actually intend the pale stripe between the car tails as a design element? No criticism if you did. It just looks like it was either a mistake or that the design is in need of one more stripe going horizontally, so one can tell it was on purpose. Otherwise I do indeed like you woody wagons.
