For a production of Crazy for You, the design calls for a large backdrop of new york. Its 18' tall by 30' long. I have no idea how to do this one. Normally building this wouldn't be a problem, but it has to be moved offstage. I have no decent flyspace and not enough money to afford a fabric backdrop. I'm thinking of using foamboard with a 1x3 frame and hinging the pieces together so it can fold up for storage. keyboard art: /\/\/\/\/. This way they can be straightened out yet compressed for storage backstage. But how do i keep them standing?
