If you belong to a fraternity, no doubt you have an official logo and maybe an official flag that your fraternity has already approved. However, you may be designing a different flag for a specific event or even just for fun. No matter the reason for the design, make the design a good one by following a few rules.
Always Follow the Frat's Style Guide
Fraternities usually have style guides that dictate what fonts and colors should be used in official designs. Even if the flag you're designing is meant for use among friends in the frat, it can be seen as a representation of the frat. Stick to the approved colors and fonts so that you don't have unnecessary pushback that makes you change the flag yet again.
Make the Design Easy to See
School seals, historical information, and other tiny, complicated graphics won't be very visible to people unless they are staring right at the flag from a few inches away. Keep the design simple, bold, and easy to see. Think of the symbols that your frat uses and see if there is a way to center the flag around one of them.
Show Unity With Other Frats
There may be rivalry and you may have your own frat pride, but in the end, you're all part of the Greek system. Find a common thread in the designs of other frat flags at your school and incorporate that into your design.
Don't Make It Half-Baked
In 2015, the city of Pocatello, Idaho, gained notoriety as having the worst city flag in the nation. The flag, a white background with fuzzy purple mountainish graphics and the logo, "Proud to Be Pocatello" in clashing colors, isn't even an official flag, but one that just kind of was there and got used. (The city is trying to design a new official flag.) Don't treat your flag design the same way. If you throw something up there because you think you need a flag now, that design is likely to stick in people's minds. Take your time and make the design one you want to keep indefinitely.
Keep in mind that it's a good idea to get your flag design approved by the fraternity before ordering mass quantities, even if the flag is meant to be informal. You are dealing with a public entity's reputation. And you never know -- maybe the design will be so fantastic that the fraternity will want to use it for other events.
