I have several 9 1/2 x 5 3/8 Mead notebooks that have lines on the front of the page and quad ruler on the backs of the page. I made a fabric cover for it so the notebook could be taken out when the notebook is full. I write down all lists, to dos, ufo's, guild meeting notes and general figuring layouts. I have about 6 notebooks completed thru the years. It's great to look back for ideas and inspirations.
