You are definitely not a newbie! You could maybe classify yourself as "advanced beginner" if you want.
I have been quilting for over 30 years and there are still patterns I wouldn't attempt...I would call myself an experienced quilter...but not a master quilter.
Really, as long as you enjoy the quilting you are doing there is no reason you need to give yourself a title...
you are a quilter just like the rest of us that make quilts.
