The only thing I have ever felt guilty about is the spending on fabric (I got a little too addicted to that LOL), but I have cut down on that and am now using what I have to make things. As long as you have food on the table and the house is livable with happy kids sew as much as you want. My DH has been told by me that I need this or therapy and he chose quilting LOL. You need to have a release from stress and while others bake, I sew.
