OK, I involved a professional. Rational for choices follows:
- 2 colours is cheap, so black shirt with white and red printing is the best option.
- Printing to the sleeves adds cost, so single HUGE QR on the back with the logo above, url and catch phrase below.
- Logo for freeems and diyefi and catch phrases on front, keeps it simple and pays homage to the community project, too.
So here are my low-quality mockups from the high-quality EPS files that Rob kindly created for us:
Front:
Back:
The community catch phrase has been updated from:
"TRUE Do It Yourself Engine Management"
To this:
"The Do It Yourself Engine Control Community"
To reflect what it's all about. Before it unintentionally implied DIYEFI.org was an EMS too.
