I have this cheap little hardcover notebook, which I've been using for general project, meeting, and life notes. It began to fall out of its cover, and I think it's a little tacky, despite the skydiving theme, so I decided to repair it while also re-covering it...
I used a scrapbooking paper that I wasn't especially attached to, but had a fun pattern and good color. For the spine, I used a dark-blue, thin, plushy-velvety material backed with paper, which I also bought in the scrapbook papers. This was the first time I'd used it, and I recommend it. It glues very well and has a great texture.
I repaired the text-block in my home-made book press:
The end-sheets, which are glued to the inside of the cover and help hold the text-block in, are the same paper as the cover... it comes with a different print on each side.
...and now my old, falling apart notebook feels completely new!
