Turn on some music you enjoy while being in your sewing room and sew to your hearts content. Like somoene suggested sew for 15 - 30 minutes. Kind of like a chip-you can't just have one....can't just sew for a short period of time. :)
I think we all go through slumps. Just dive back in and think about all those little kids that you are blessing because of you sewing. That is awesome! ;)
