This past holiday season, I found this great journal at Borders. It's made by Paperchase and it's entirely brown paper - otherwise known as "kraft" paper. The size is 6" x 8.25" and has an black elastic closure.
Now, back to kraft paper. I've been searching for heavy weight kraft paper. Low and behold, I went to craft depot today and found this. This should be enough to last me awhile.
