You all know this picture and these 2 designs. By dumb luck, I met a friend-of-a-friend who was really good with Adobe Illustrator. So I asked him how these two shirt logos were probably done. He was able to describe the way they were most likely designed in Illustrator, and generally agreed that while these designs were at the level of any skilled Illustrator designer, they probably were above the skill level of 95% of the folks selling shirts on FB.
And if you look at the first 10 or so pages of the top selling shirts on Teeview:
.. you rarely see any shirts comparable in complexity to these two shirts above.
So I ask... do high-level Adobe Illustrator skills really matter when it comes to having successful Teespring shirts?
Do well designed Teespring shirts really sell?
