T-shirt Design Brief
Aloha! I am starting a special project to help raise money for small orphanages throughout the world with the sale of these t-shirts targeted towards other adoptees from 21 different countries.
Concept:
1) Have country in the background
2) Have the world "ROOTED" in the foreground
3) Use the country colors in some way so that people would better be able to identify the country
4) Not too patriotic and no use of flags
5) Really wanted the shirt simplistic but also make the word "ROOTED" pop.
6) I initially used the bar going across as a moniker cause it provided "stability" like a root because actual roots seems to be on many t-shirts. I wanted something more contemporary.
Challenge: I did some mockups in canva for these 4 countries (Thailand, Columbia, China, Vietnam). The base design should make sense when looking at the 21 countries together but figuring out how to use colors and fonts was difficult. Also what color the country should be. I will be doing three colors of shirts (White, Grey, Black) for each of the 21 countries below.
Thanks so much for your help! Excited to see what some of you come up with!
