After seeing my book Spiritual Calligraphy, several people wondered where to get prints of the artwork. I opened up a shop on Etsy at http://www.etsy.com/shop/stevehusting and prepared several artworks for selling online. It is now open, so please come in and browse!
The book turned out so well! I was amazed at the Print-on-Demand quality of the printing (this company was founded by the late Steve Jobs, after all). The book can be found here: http://www.lulu.com/spotlight/stevehusting
I do not carry any for-sale copies of my book with me. This is Print-on-Demand publishing, in which the book is made only when someone orders it online; it is not mass-produced.
