I think everyone has been there at some time or another .. Go outside go to the mall walk around and get some inspiration. Or if reading a good book is yours, do it ...Take a mental break from sewing and seek as I call it "the Calgon take me away moments". LOL
Sometimes when I am at work an idea comes to me and I scribble it down really quick, put it in my purse and forget about it . Then I decide my purse is getting awful heavy and I need to clean it out and there are some inspirations that help me out.
