I really cant describe this theory or method of making patterns but if you asked me to do it i could. This website is really useful to help understand and create your own patterns. If i have enough time i will try and create some patterns using the info from this website. It has some really easy to understand animations that are quite an interesting easy way to show how to make the patterns and how they look once completed. Obviously you can choose your own shape or design for the patterns, these are just used for simplicity and ease of viewing. You can rotate by 180,120,90,60 degrees, reflect horizontally or vertically, glide horizontally or vertically and change where you do all this from: either the center or a corner for example.
