I love this magazine designed specifically for those quilting those quilt tops. Machine Quilting Unlimited is a subscription only magazine you might find interesting : http://www.mqumag.com
The magazine has just published my article on making thread color choices...Thread: The Linear Paint! This topic could easily be a book, tho this article focuses mostly on how complementary (to fabric) thread colors in differing values might be used for impact. Shown here is a snippet of the article. Contact mqumag.com for past issues and subscriptions.
