Sarah Hornik has published a new e-book called "100 Color Ideas for Glass Beadmakers." I think Sarah's color schemes are TDF so bought it immediately. Just finished my first read through. The 100 color recipes are terrific, but the "tips" Sarah includes on most of the beads are fantastic - the bonus icing on the cake. Highly recommended!!!! FYI Sarah is not a personal friend, just another lampworker whose work I greatly admire.
