First you moved and its right after the holidays both are exhausting . Then there is the slow down for winter time. We all feel it, we just don't pay attention.
When I have a slow down , I either take a break and don't even think about sewing or doing any thing like it. I clean things,(in other rooms) and read for a few days. Then I watch maybe a video on youtube or The Quilt Show that kicks in my "want to" normally. And gets me thinking creatively again.
