Same here. When it occurred to me how I could use it I looked all over and couldn't find them again.
Another thought. You know those 10x10 shelters that have red and white, ect, striped tops ? I wonder if you could just order a bunch of replacement tops for them and use them ?
I made my own Clown/circus Tent and it looks great
I have a couple ideas for you if they have not been mentioned yet. First, not to sound non patriotic or un-American, (please no bashing, it's just an idea, not for everyone.) Have you thought about trying to find some large fairly inexpensive American Flags & removing the blue square and stars? It would have to be a large flag but maybe? Second seems like a no brainer to me. How about simply buying a bolt of inexspesive white and a bolt of red material. Cut them into strips about 13 inches, which I believe is a standard size for striped circus tents, and then sewing them together. I am sure someone in your group has a sewing machine. If you are just using on the walls and not ovr head, you may not even need to sew them together. You could simply over lap them on the wall in the striped pattern.
Just two ideas that came to mind.
