It turned out even better than we all expected! I wish I could take credit for it, however, Whitney was the master mind on this project! Here's the how to:
-she bought about ten pairs of curtains from Ikea to cover the width of a basket ball court
-cut curtains into strips about 6" thick
-she sewed two strips together (short end) so it was long enough to reach from the top of the net to the bottom. Depending on how high your backdrop needs to be this might not be necessary.
-dye strips in a bucket of dye (each batch sat in the dye for about an hour or so)
-hang them to dry (note: they drip so make sure you hang them somewhere where dripping isn't an issue...like the grass) She took pvc pipe and made something to hang them on.
-She than took wood, placed it at the top of the net and draped the strips over it so they hung at different lengths. She stapled them in placed, and continued to layer the strips.
