The one piece of advice I have: use an Accuquilt cutter. That one thing saved my sanity. Oh one more piece of advice: buy more fabric choices than you need. Some of them don't pass the test once you add them in. I used phone pictures to send to daughter so she could say yea or nay with each new introduction of a fabric choice. And if you didn't know already, phone pics are a great way to see if your colors go together.
