Don't give up! You have a great teacher and a great group of quilters to help you along. I'm sure they would be happy to share little hints to help you overcome what you "think" is wrong. Most important thing of all though is to relax and have fun with the group and enjoy the quilting. I asked a question about hand piecing at my BOM group and instead of getting an answer :D I got at least a half dozen ideas on how to get my machine to stop eating my fabric ... which is why I was hand piecing in the first place. Quilters love to help newbies so go and ask questions and enjoy.
