I would not recommand to start with a lone star when you are a beginner. I made my very first lone star when I was quilting about one year (also still a beginner) and it was very difficult, because there are different ways to make them.
Now, I have more quilting experience and I made more lone stars and I also teach how to make them.There is a tutorial here on the quilting board in the tutorial section.
It's just a friendly advise,please don't take it the wrong way.
