Is it possible that your new space lacks something? My sewing room turned into a total mess and 7 cats couldn't find one mouse. So I spent some time in the space to figure out what was bugging me. DH helped me empty the room and rearrange all the furniture into a nice setup. He was doubtful that it would make a difference but even he is surprised at how "happy" the room is now. Maybe you need to really "CLAIM" the space and make it your creative haven. Then start slow and have fun.
