I made this book to brag about my Grandson! The covers and spine are matboard covered with scrapbook paper 1/4" larger than the tags that I cut for the inside which are 8 3/4" x 5". The tags were cut from cardstock, then covered with scrapbook paper.
The spine on the book is 4" wide to accommodate 8 signatures of 2 tags each. I used a striped paper to join the tags together, then put 4 eyelets along the "spine" that I created between each 2 tags and used ribbon to tie through those eyelets and then through the eyelets on the spine of the book, tieing the ribbons into bows outside the spine.
I've scrapbooked the first signature (the first 2 tags, front & back) and will be posting the rest of the pages as I finish them. I've really had fun so far!
