Another good source of "blenders" or "blendables" is Kona Bay Fabrics <
[email protected]> (yes, they are in Hawaii). They sell to wholesalers/stores, but you can find them at nice quilt shops. They are a bit too pricy for my everyday piecing or quilting, BUT they are BEAUTIFUL! and soooooo varied and I'll surely buy some when I have a quilt needing that special touch. Their catalog of designs and colors are wonderful!!!
Enjoy perusing.
