lots of quilters finish their own quilts. it can be a lot of work though. maybe she can ck with a Senior Center in your area for fellow quilters or ask at a quilt shop if they have classes. learning can be fun. library books and the internet are great too. watch any shows in t.v. on quilting that can be found. I'd say most of us taught ourselves.
and yes, having someone else finish your quilts can be expensive, especially hand stitching binding on.
take it slow and have fun. good luck.
