An eBook is a PDF document that you download to your computer. From there you can either read/use it straight off the screen, print it out on your home printer, or take it to a store for printing. You could even just print out the pages with patterns and read the rest off your screen. It's completely up to you!

This is one of the most comfortable, softest T-shirts I own. And the color goes great with just about everything. l love it!
