I'm not the most experienced tech savvy person, but I found this new app that I just love, love, love. It's the Goodreader App! I'm always downloading new crochet or knit patterns, printing them every time I want a new copy so that I can mark on them with little notes, etc. this new app is for PDF files that you can save but you can make notes, etc on them. I know that I haven't learned everything about this app, but I'm going to try!
Blessings & Peace,
