I make my own bags and cloths. I go to Spotlight (its a haby/craft/furnishings chain here in Australia) and I pick through the remnants bin. I have a beautiful piece of silk in watery greens with darker green overprinting that I got for $1.00 and all I had to do was hem it. I have also found small sections of velvet, satin, lace, organza and so on which I use for bags or cloths depending.
I try to match the bag to the deck so the bag for my VRG is pale pink satin inside with white lace material on the outside, Froud Fairy Oracle is in a hand dyed merino wool bag I knitted, the Pocket Goddess is in a purple velvet lined with shocking pink (almost neon) satin and so on.
The only thing I would say about cloths is make sure they don't crease badly and are easy to launder (voice of experience here...)
