while doing some research myself I came across this fella (see link), though he is in Sanur so that may not suit you if you are going to be staying over the other side of the island.
When I stayed at The Lokha last year I walked past this shop every day and it had a good selection of fabrics to choose from.

I guess if they dont have it I'm sure they can source it for you.
