When my kids were little I found time to quilt when they napped etc and also some other times as well. As long as they were busy I would get some sewing time in.
My kids and hubby seemed to realize that sewing time for me made me a happier person! That, in turn, made me a nicer wife/Mom LOL
Now that they're grown I have more time- but I don't think I'll ever have as much time as I'd like, say 24/7 LOL :D
