Welcome aboard and I know what you mean about being a bit intimidated. The work many of the members do here is incredible. I'm still working on my first quilt and everyone here has been helpful and friendly. Just keep in mind everyone here is human and at least some of those doing the incredible work probably feel the same way when they look at other's work. Just do the best you can and remember this is supposed to be fun. You'll end up with a nice quilt when you're done.
I'm going to parrot what some of the other's have said. Do a search of Ohio Star quilt images. You're certain to find at least a few ideas to inspire you.
