I created a very simple journal with a composition book, cardstock, pattern paper, star stamp, and a few embellishments.
You can create your journal to represent your style. I kept my cover pretty clean of embellishments because I do travel with mine pretty daily in a messenger bag.

Even add a photo in or on the journal of some of your favorite books.

I only used one side of the paper, so I could add additional writing to the back of each review if needed.

The most time consuming part of this project is stamping the star. My stamp was only one star so I stamped it 15 times on each page. To avoid having to count the lines on each page for spacing, I had a scrap piece of paper with the stars marked and I slid it behind the page I was working on and you can see the placement through your page without having to count.

You could use any design stamp you have on hand that can be colored in...maybe an O, a small balloon, a butterfly, a bee, etc.
Send me a note if you post your book review journal, I'd love to see them.
