I wasn't a notebook person until recently. I used scrap paper for the occasional to do list but mostly my system was electronic. At conferences I liked to have a notebook and everyone else seemed so excited about their notebooks that I figured I'd try it out. Staples has this lovely one - cardboard front and back, I want to say it's made of recycled materials but I'm not positive that's true.
My favorite part of this notebook is that it has three types of paper - lined, blank and graph. They are in two sections. I used the front half for miscellaneous stuff including these fun math problems! However, it's starting to fill up and people were talking about Arc Notebooks on twitter so I thought I'd check out my other options.
These notebooks are cool! You can pull pages out and pop them back in as needed. That means that I can reorganize. One part that is frustrating about my current notebook is that there are a bunch of lined pages followed by a bunch of blank pages followed by a bunch of graph paper. Sometimes I want graph paper next to my lined paper.
The accessories pop right into place!
