Fi9nd a shop where you are comfortable and like the teacher then sign up for a class that is suitable for a beginner. I am a newbie to sewing and quilting and just took my first class this weekend as learnt alot. You will find friendly people and our shop limits the class size to no more than 8 people so you get attention to the help you need so find out the class size. I am also shy but in order to come out of the shell and learn you need to sometimes step out of your comfortable zone.
