How can I make the Front and Back cover a wee more durable without interfering with the area in which the pages inside are connected?

I just watched a video to retrieve suggestions and it made me more comfortable with the way I was brainstorming to make my Conga. But, being the highly advanced and professional intellectual I am, it’s only appropriate I find a method to make the book sturdy. So basically how I plan on assembling the book itself is get the cover ready, put glue where the spine is, leave it for a few hours or so, and Pocca Boomdada Seemssyada, I’ve got myself MY FIRST CONGA BOOK, AAAAAAAAAHO. However, if I stop there then the cover will be JUST paper and that’s a big no no. Suggestions PLEASE?
