A lot of online stores have fabric sorted by manufacture and collections
Thousands of Bolts - has their fabric sorted by color - you can search my manufacturer
http://www.thousandsofbolts.com/inde...18&ParentCat=2
They have 3 other links - when you select on a fabric - one is a color matcher -
Although I have not used it Moda has this link
http://moda.fabricmatcher.com/
That might help as well.
But I can't tell you how many times I have gone to Joann Fabric only to leave with nothing.
