Since she's only done your hair twice, she might feel it's a very extravagent gift. Might she be embarrassed? You know her, we don't, so do what you think is best. But if it were me, I might be inclined to give her a cash gift this year and then give her a quilt when you know her a little better, maybe for her or her child's birthday. I like the idea of a quilt for her child.
