I have those times as well. Instead of pondering it I have learned to just let it go. I clean up the sewing room and organize it so when the mood is back I am not stopped by the mess in the sewing room, I get on the internest and read and talk like I am now with other quilters and see their projects and that gets me motivated again. I finally found the quilt last night I want to make for our son who was wounded in Afghanistan. so it comes back slowly some times but thats ok. Just put it away...forget about it. do somthing else. You will get back to it. Have a sunny day.
