The "empty nest" doesn't necessarily mean you'll have much more time. My DH always said "there'll be time for us later." Well, he was wrong because he's not with me now. He passed away 11 years ago, and I find myself still working (at my age of 70). So, if you have any "free time" you should cherish it and get done what sewing you can. I always bought fabrics so I could quilt and sew when I retired but it sure doesn't look like that's going to be any time soon.
