Each uppercase has a matching lowercase, only without the face but the plaid is the same one.  None of the plaid patterns are repeated in the uppercase letters, each is different. The punctuation is not the same patterns as the letters again each is different. Only the numbers have a few repeated patterns. Quite frankly, I ran out of plaids so had to repeat them. LOL Each of these plaids I used were made by me and are my copyright patterns.

I used a font called Face It for the faces and two fonts for the rest. The uppercase were a font called Basic Font Sample  and for the lowercase and the punctuation are from a font called Berlin Sans FB Bold. A few of the lowercase were too different so I used the Basic Font letters smaller for the lowercase such as with the "w" & "y". So all in all, it's not just one font but tweaked and manipulated. I decided to make them multiracial and just chose at random which face to color to use. There is nothing behind the expression on each face or the color of the face. I was paying more attention to mixing the different plaids and not reusing them.
