Well I am a full-time student...work part time and have 6 kiddos and DH. I sew because it relaxes me. I usually sew after the kids go to bed...and dh works early hours so he goes to bed early as well. SO I have the house to myself and sometimes I probably should be cleaning or studying ...but sewing helps me.
I can sew without thinking ..so night time is a good time. I study better during the daytime hours.
