For the inside, I added just a couple of pieces of the envelope to make flaps, which I secured to the main cover with some teal colored duct tape I found lying around. Instead of adding more layers of the cardstock to create pockets, I made some strategic cutouts to accoummodate credit cards, slips of paper, and a pen clip.
Here's what it looks like with stuff put into it:
The final touch was the addition of a Rhodia No. 8 notebook. I'm glad to say it fits perfectly! Lots of pages on which to jot down notes and doodles throughout the days.
Now, the only thing is to make sure I use it each and every day. Knowing that I put a lot of work into making it will help with that. Not only do I want to keep a good outlook on plans and projects for the year, I also want to see how the cover and tape hold up to daily use. Never to late to improve, right? Just the right attitude for the new year.
