This is the "European 4-in-1" pattern. It is most likely the first pattern that I will be using in this project, as it is the one I am most familiar with, and it is one of the most simple ones in existence.

Here is a little background on this pattern, taken from the CGMaille website:
"European 4-1 is probably the most common weave used in maille-dom, due to its simplicity and ease of construction. It's most famous for being the weave used in European knights' armor. European 4-1 can be made using several techniques, such as one-ring-at-a-time (ORAAT), one-open-one-closed (OOOC) and others."
