I had a 3 year hiatus from quilting and anything crafty which started with a badly broken right leg. My mojo totally went away while most of my energy went to recovery and then rehab. After that I was just busy doing other things, plus the thought of all of my unfinished projects was overwhelming. Last fall some of my close family had some tough times and I felt the need for some craft therapy. Finally!!
I only sew when I want to which is hours some days and not a stitch on others, but I'm pretty focused on quilting and finishing UFOs now and find I am happiest when I can work in a few hours a day. My youngest is 17 so I have the luxury of lots of time while DH is still working, I do feel some pressure to take advantage of it now because life can throw some curves. But mostly I feel lucky to have the time and means to enjoy it!
