Hi, keep it really simple and success-oriented. I was just talking to a co-worker today about my god-daughter's first big quilt. But, first I started her with a fusible applique wall-hanging. It was pretty simple. She's known to iron and use fusible web since she was 4 and she and I constructed a closet for her American girl doll. So, I went from there. she saw a picture in one of my books (I preselected four or five and let her pick one) that was simple fusible. After she picked the fabrics from my stash, she traced the pattern onto the paper of the fusible, then ironed the fusible to the fabric, cut the pieces, placed and ironed them onto the background. Then, she picked the thread (she was 8, think sliver, metallic, and I set the speed on the machine to slowest and stitch to satin, told her what to do and stood back and let her go. She preferred sewing to swimming that day. Since then, she made a double-bed quilt for her bed. I quilted it for her so could "fudge" her not-quite-square into something sort of square. She loves sewing, so I expect your gd will too. Because the goal if fun, not necessarily perfect. If she has fun, she'll want to do more and then, each time, you will help her learn the 1/4" straight seam allowance. Also, let her learn to "unsew" if her seam allowance is really off (say 3/4"). Lily didn't seem to mind this part at all.
