The concept of pattern is to make something that repeats over and over again to make a design of some sort so that it is recognizable among people. For example, the number sequence 0, 2, 4, 6, 8, 10 is a pattern that repeats, makes a design, and people can recognize. Hope this helps!
do you have anyone you look up to? someone who is a big inspiration? these people dont have to be real people, or the could be famous, or just everyday friends.
if that dosent help, maybe google a character generator? ive done that and it seems to work
