The capes are pretty easy. First look at Brak's nifty tutorial for the ROTJ cape to get your cape dimensions:

Then peek at my sorry first attempt at an ESB cape here (I made the stripe horizontal instead of vertical, D'OH!):

Scroll down a bit and look at my version 2 capes. Just ignore the part that mentions dying the whole thing green, that was my error from looking at the movie's funky lighting.
Get some light brown flannel and some Orange spray dye (Rit Tangerine works well too with a spray bottle) and read my rambling tutorial within that same thread.
