I love books & have been collecting children's books from the moment we got married in hopes that I would raise a little reader too. Fortunately E LOVES her books, but in no time her board books were showing some serious wear.
After watching them die a slow death I figured I needed to do something to help them last a little longer. I took a queue from the library & decided to reinforce the binding with tape.
Simply take clear tape & tape the length of the binding. Take your time, you don't air bubbles & you really only want to do this once, especially if your book is already battered. Once you've applied the tape to the binding carefully smooth it down on either side.
When it's said & done you can hardly tell the tape is there, with the exception of the end where the tape was broken. I first tried this several months ago & the books are still going strong. If you've got little ones at home this is a great way to get more life out of their books. You might just love it so much you do all the books in your home.
