So when I went to visit my friend in St. Louis for Spring Break, I made this. I haven't posted it yet because I accidentally left it there and haven't gotten it back until now!
I sewed sets of 3 of the longer bar cards together (the ones that say "I'm So Techno"), then sewed two of those strips together 4 times.
I cut slits in the base and inserted the other cards, then glued (or taped with double-sided tape- I tried both and don't remember which worked better and therefor which I used the most) them to one another.
Pardon my mess.
Thanks for looking!
