The main challenge when different designs has to go together is to keep a kind of harmony, for instance not use too many colours (that distract the eyes) and make something easy to remember. I will post few ideas as soon as I will finish a work which is almost finished (and I can't wait to forget about it!!!) Hope in a couple of weeks
I apologize I was reading [the word "code"] in the opposite way...and that's brings me to think if other people would try to read it like i did...what do you think?
