I am going to be doing involved in the pre-stampede parade here in Calgary at the beginning of July. This parade is a huge event here. We are going to be walking the 6km parade route entertaining the crowd as they wait for the big parade.

Any ways one thing that is big here to get the crowd going is to say Yah Hoo! There is always some clowns or cowboys that hold up these signs that say Yah on one and Hoo on the other. So to make a long story a little shorter. I was going to run up behind this guy and hold up a sign that says Woo Hoo instead making it a like he is telling them to say the wrong things.

I want something that can roll up so that I can pull it out of my pocket, unroll a little to show Woo, then more Hoo and then Wally at the front for Wally Woo Hoo, which is my name.

Does this make any sense? So what help with is what should I use that I can roll up and write on?

USE A CHEAP WHITE WINDOW SHADE.

the kind that is plastic and has a spring-loaded pull on it so that you can close it quickly and open it quickly. you might be able to write on it using acrylic paint or permanent marker without it smudging, but I'd test an area first to determine what to use. you can get it cut to any size you want, but I'd make sure it's big enough for the crowd to see clearly at a distance
