I've talked with Corey and I'm going to talk with my advisor as well, but 25 and 1089 can probably ALSO help in with button-making. I know I'm not part of the ECDU, but, like Shaivya said, I did help make the buttons for our team this year. I think your proposed meeting time is a good one. Definitely lunchtime, since that seems to be the most 'unstructured' part of the day.
Anyway, like I said, I spoke with Corey and he forwarded me the image Coco had made for the button. I took that and edited it a bit, and came up with a final image. The white circle is just to show you what would be on the face of the button. All constructive criticism and anything you want fixed/changed/edited is completely welcome and expected. After all, you guys are the ECDU, you have to like it.
Anyway, here you are. I only take credit for putting it all together, the image design, quote, and gradient background are all Coco's.
