Where has my arty mojo gone?

I am struggling creatively at the moment. I'm not sure what is going on, but I sat in my studio for about an hour on Sunday and couldn't find the inspiration for anything. I then dumped all my card making materials on the dining table hoping to find the enthusiasm to do something in front of a dvd...no such luck. What is going on?? I really want to create and hopefully get something to show for TishTash accessories....but no such luck right now. I just have to hope it comes back one day soon! In the meanwhile I'm going to embrace catching up on my massive reading list ;)
