Hi! Just my two cents... I hope it helps even though it's a bit late. Please, please, please, don't be embarrassed by your work. Trust me, we've seen it all, and a lot of it has come from seasoned quilters. If your quilter knows you are new, she/he will probably go out of her way to be sure you understand- it will help you both, on your first quilt, as well any future quilts you will have quilted. Ask your quilter to help or to give further instruction if you are unsure. She wants her work to look as good as you want yours to look, and the more you work together, the more beautiful your quilt will be. Most quilters I know are more than happy to help their customers, and I for one, love to teach people things about quilting that they didn't already know. Just keep asking questions!
Don't forget, we were all new to quilting at one time, so be proud of what you've accomplished. A lot of people don't even make it to the quilting stage- they give up before it gets that far.
Welcome to the world of quilting! I'm sure your quilt will be absolutely stunning!
By the way, there are bunches of videos on youtube, try doing a search on another quilting subject, you might be pleasantly surprised by all the information available there!
