I can't remember a time when I didn't have a journal/diary/sketchbook on the go. I still do, thought my journals these days are mostly filled with little drawings and ideas for future sewing projects, notes taken at special events. They're filled with endless lists.
If you're feeling a bit in a creative rut, try switching up your medium a bit. I love embroidery, but get so bored so quickly. Instead, swap your fabric to photographs or images from magazines. These are incredible works of art, stitched onto paper.
