ShiDianYi Gold Shimmer Sequin Fabric Photography Backdrop (4FTX6FT)

If i want this to be 20 ft. high (as to fit the height of a stage) would i order the 10 x 20 ft or the 20 x 10 ft? how is it hung up?

Is this thick enough and large enough to use as a party backdrop?

is there an option to get a 3 inch pocket on top and on the bottom as well?

Can this be used for a bedroom curtain and if it can be which size do u recommend?
