Translate the word Pattern in Greek?

What's the translation for the word "pattern"

I'm talking about on a shirt or even pattern of thought - like recognizing a pattern.

I tried google translate but it keeps giving me mixed answers because when I google image the word, patterns don't really show up.

Update: I want to say either:

1. That is a pattern on his shirt.

2. Your pattern of thinking is very interesting.
