Remember that she's used to her independence too and she considers herself an adult now, not a child to be taken care of. If she's not working while she home then perhaps she should take over some of the household chores giving you MORE time to sew. Sharing the chores will give both of you more time to enjoy each other and individual interests. If she gets a job then sew while she's working. If she insists on being an appendage then buy her a machine. Set boundaries right off the bat and tell her that you're taking a few hours a day to sew---ALONE.
