You ARE in good hands. Is she going to teach you more than meandering design??? If so, don't give it a thought, you'll do fine. If she's going to teach you more detail, then I suggest you buy 2 old sheets at a thrift store and some cheaper batting and have her let you "practice" on that. It'll make you more comfortable....you can play without worrying about losing $$$$. Then have her help you on a real quilt. Oh - I did this and even "drew" a quilt design...so I'd learn control within the designs.
