I usually don't ask questions here, but I can't seem to find a satisfactory answer anywhere.
1.) When do you use borders, when do you not?
2.) When do you use a thicker border, when do you use a thinner border?
3.) How do you decide whether to use a black or white border?
4.) When do you use a letterbox border?
5.) Any other border-related knowledge to share?
I'll be glad if anyone can just point me to a useful website or tutorial if you can't answer the questions specifically.
