For signage at our most recent event at REN, I decided to try something new and paint on the floor. First of all, painting on the floor is really fun and I highly recommend it (as long as you test in an inconspicuous area first!). I used a mixture of about 50% acrylic paint, 50% liquid dish soap to make it easier to wash off. The thinner consistency also made it easier to paint with - a nice bonus.
After lettering the large circle (approx. 5ft diameter), I painted arrows, illustrations, and lettering that explained what each area was. Below is a photo of the whole lobby area (this was mid-setup, so don't mind the random things scattered around!).
There were a lot of people walking around that night, so by the end of the event the paint was looking a little worn. It was all still legible, though, and I actually like the worn-in look.
If you're interested in seeing what the rest of the event looked like, you can watch a short video here.
