HELP 20/2 spun silk

I normally buy my 20/2 silk from WEBS, but have been frustrateed over the limited selection of colours, and I am NO DYER!!!  Trust me on this!   I am looking for a source for more colours, and, preferably NOT in skeins, but cones.

Anybody have some ideas?  I have tried all the "usual suspects" like Treenaway, Halcyon, Yarn Barn, etc etc.  Anything I've missed?

I am weaving a set of bookmarks in liturgical colours and would like to do a set in "rainbow" warps for the members of Episcopal cursillo.

thanks, Nancy C.
