I really like Splendor as a staple for silk, and they have such a good color graduation. But, I do confess that I'm loving using the Needlepoint Inc silks - they're really nice, also with a full color palette.
Gumnuts - the name, carried by Custom House. They've been around here for about 8 years. Heard a few months ago that they're getting rid of their more variegated line, but will continue with the shaded lines. They have lovely silk, fine silk perle, silk buttonhole twist, and some blends with wool or mohair - great on larger count grounds. Beautiful to stitch with and hold.
Sounds nice.
