Russell, that's what I sent to the printer....but there are several problems. Vistaprint says that resolution is too low (but Avanti got the same picture to work for his backdrop) and they can't print a banner on anything but vinyl. I would prefer card stock or heavy paper.
If my walls were straight then 10 ounce vinyl might work but my walls are sloped. I guess I could use wall paper glue but they can't advise me on that so I'm afraid to order it.
I have a Groupon for $70 worth of printing at Vistaprint; I paid $17 for it.
