As someone who first turned a sewing machine on less than 2 years ago. I can relate. I would go with the advice to find forgiving patterns (like D9P) and let her go. The joy of creating, out weighs the perfection required for experienced quilters quilts. Working on consistent seams whether 1/4" or 1/2" inch will come with time. As I learned doing "shared blocks" for my Bee. Not all 1/4" are the same and mine is a fat 1/4". I have to sew what I think is 1/8" to get the same size blocks as most of my friends.
