For both: We used the MyCreations Cubes from CTMH and divided each of the sides. This means that 3 notebooks can be made from one set of cubes.
The monogram is the Baroque Alphabet. The girls and I fell in love when we saw this stamp set--stunning in person-well worth the investment.
Also needed are a pen for inside, a short length of ribbon, and 3 x 5 top-glued notepads, which I get in a pack of 12 from my local Staples.
The notepad is glued inside and the length of ribbon is looped under the notepad when it is adhered down. To bind, you need a Cinch or a Bind-it-all or similar. I like my Bind-it-all b/c I don't love the round holes made by the Cinch. Totally a personal decision there. People either love the rectangular holes or hate 'em it seems.
Left Notepad--paper from CTMH Level 2 Magnifique paper set and opaques. The larger mat piece measures 2 1/4" x 3" and the stamp is on a 2 x 2 square.
