My friend, Sandy, fellow pattern designer and ex-co worker just started a new blog. She has a very nice tutorial for making quick and easy fabric coasters. http://sandyfitzpatrick.wordpress.com/2010/09/17/coasting-along/. So take a look and while you are there, check out the "Hanging by a Thread" article http://sandyfitzpatrick.wordpress.com/2010/09/20/hanging-by-a-thread/. It is about an art piece hanging in the NC Museum of Art that is made from 5,184 spools of thread. The artist Devorah Sperber has a wonderful collection of photographs on her website of other art pieces made from spools of thread.
http://www.hissyfitzdesigns.com/, and her business is called Hissyfitz Designs. I just love the name and it fits perfect because her last name is Fitzpatrick.
