Here is the link to Shirley Botsford's book, which I hear, is the best available information for making a quilt from neckties.

I find buying some of these books are very helpful. Ties are an entirely different fabric source. This will not be like cutting strips of fabric.
Here is an interesting site with discussion you might want to read, especially planning for the future, and washing the quilt.
