My husband and I take turns giving each other a little bit of alone time away from kids and chores. I will take the kids out to the park or on an excursion so he can have a few hours of quiet when he gets home from work, then he will give me a few hours of uninterrupted sewing time downstairs. Unfortunately, I really don't do well when interrupted while sewing so my kids are not allowed to play in my sewing room. It really is my private space. I stopped watching TV in the evening and that has freed up a lot of sewing time but I don't always have the mental energy to sew in the evenings. My favorite time is on the weekend early to mid-day so I arrange that with a little give and take with hubby.
Some good suggestions here.
