Though some chapters opt to make their own signs using felt and markers, the best choice for a professional presentation is a Sign, Flag or Banner created by a pro. This page lists the latest sign designs available for Tau Kappa Epsilon members.
With the two lines of text available on the TKE Vinyl Banner, you can go into a little bit of detail about what the fraternity means to you and your fellow members. For instance, you can add your motto "Better men for a better world" and the current philanthropy that your chapter is working on. You could also enter more specific information about your chapter, like the year it was chartered.
Every couple of years or so, you should update the flag that's hanging or flying in front of your chapter house. The 3 x 5 Flag is a good choice because your Greek letters are large and it includes both of your fraternity colors (red and silver grey). The organization's letters are printed even more prominently on the Big Greek Letter Flag.
One of your to-dos early on in the semester is to buy Tau Kappa Epsilon Signs, Flags and Banners. They are a colorful introduction for interests to your fraternity, its values and notable history.
