First let me say that I only have to justify things to myself and have gone back and forth with this question in my mind - If I made my living quilting then it would definitely be justified but I don't. There are so many things that I would love to have (another great machine, more space,as there is never enough, more time, as there is also never enough). So I guess the answer is when I win the lottery and will not have to justify anything to be able to have it all!!
