In nature, almost everything can be reduced to an elegant pattern of numbers that forms the structure and framework of grass or tree or nautilus shell.

For this reason, clothing patterns are easy to make yourself, everyone can follow a simple and regular pattern. For this Patterns list, add a few more sites with a summary for each.
