I cut a piece of white cardstock to the size of the paper and used the holes as a guide to make holes in the cardstock using an eyelet setter.
(In hindsight I would recommend doing this next step BEFORE making the holes -- I ended up having to do the holes twice!) Next, glue on some cute scrapbook paper, pictures, and any other embellishments.
I found this quote online and thought it was perfect! "Memory is a way of holding onto the things you love, the things you are, the things you never want to lose."
Then cut a slit up each one of the holes so that it will slide right onto the spiral binding.
All that's left to do is glue the cardstock onto the cover and it's done! Hopefully my cutesified notebook will make me want to pull it out often and record those memories. :)
