Hi and welcome from North Carolina! You've come to the right place for all kinds of information about quilting. These people here always answer all questions.
Your being a seamstress is a big advantage for you to learn to quilt. It's a lot easier and a lot more fun than you think. Just remember to start with something easy, like a 4-patch or a 9-patch pattern, and with something small like a lap quilt or a baby-size one. And, remember that your 1st one is allowed to have a couple of little mistakes. There are no quilt police!!
We all make mistakes. That's what they manufacture those seam rippers for!! Just enjoy!!
