First, take a deep breath--if you're like all of us on here you're in for a great journey. I'm self-taught, long before internet videos. If I were starting out, I'd go to the library and find a book on Beginning Quilting and read it start to finish before I jumped in sewing. A basic book would tell you about the supplies you need, how to pick a simple pattern and how to chose fabric. Start small!! And please start!! You will find lots of lessons here and you can always ask any question, and remember we all started out without knowledge. There are no stupid or silly questions.
Start slow and enjoy the journey--it's not a race to see how many quilts you can make. It's to see how much you enjoy the process.
Good luck!!
