You can also get an eBook copy from Bead-Patterns. The nice thing about eBooks is that you can print out individual pages to scribble notes on.
And the prices have gone down also.
Urban Stripes has been an eBook for some time now, but I finally got the higher resolution photos together to do a POD edition on Amazon.
I personally still like paper copies of patterns, beading and other books.

When I did my first Bead Crochet book 14 years ago, I thought it might be just a 30 day wonder. Digital cameras were new and expensive, there were no Print-on-Demand services and downloads were scarce. I'm amazed (and grateful) that sales of all of my books continue as new beaders discover what they can do with bead crochet.
