This is a great source to start out with as there are so many folks here that will help you when you have a question. Also they can direct you to sites where you might be able to find lessons, sales, videos to show you how they made the block, etc. Also YouTube videos is another great site as they have lots of videos to how you the easiest way to make your block/quilt.
Also, welcome to the life of a quilter. Lots of very nice folks here, lots of newbies here to so don't feel like you're alone. No question is a stupid question as we've all been there, done that and probably still make mistakes from time to time. Just yesterday I trimmed a section to a blocks completely wrong so it went into my orphan block container. Luckily I had an extra one to replace it with. See, dumb mistakes and I've been quilting since 2005.
