When I lost DH#1, I couldn't touch thread, fabric, yarn. . . anything. I had lost my cheerleader. You just have down times. So, I would first take a trip to a fabric store to make sure your funk is in your heart as well as your head. Then I'd work with whatever I wanted to with no self recrimination. It will all come back. If you don't believe me, just ask DH#2, a fantastic cheerleader and a terrible, TERRIBLE fabric stash enabler! Don't we just love "naughty" guys?
