Here's recent page from a little journal that I started keeping a year ago. I got the idea from a woman who had a journal similar to this in a show at BookWorks last winter. My take on it is that I divide each two-page spread into fourteen squares, one for each day of a fortnight or two week period. Every single day I make a quick sketch and write a few words to highlight or summarize the day. The spread shown was from the last part of December. The book has enough pages in it to fit another year's worth of tiny squares. It's a little butter box journal, only I used a Whole Foods 365 house brand cream cheese box (which has "365" written on the cover-- perfect!). The directions to make this journal are under "tutorials".
A number of people in my journal group have been keeping this type of journal, and they all have their own takes on it. I'm trying to loosen up and break out of the squares, but so far I have not been successful, other than to paint in an overall background that sort of reflects the weather. I love this practice as it takes only a few minutes each day. Then when you flip back through the year you remember so much more than you would have remembered without the journal. It helps me see patterns, too.
