This is exciting! XRX books has just released what they are calling “Stitchips” of mine and their other books. It’s a physical thing the size of a charge card. You plug it into your USB drive and you’ve got a high quality pdf of the book. The Stitchip has a photo of the book cover on it; it’s small and makes a great gift for a weaver/knitter who has wanted the book but hasn’t been able to get it because it’s out-of-print.
I am selling these myself for $18.50 US, free shipping in the US. I will sign it, just like an author would sign a book. Please pm me if you are interested.
