Now, if you really have time, turn those boring notebook covers into something more 3D-ish. Get some needle and thread to make an awesome embroidered notebook. Your kid would also want to try this one for him/her. Make sure to help your kid when doing this especially when holding those pointy materials like the needle and scissors.
Don't stick with those ready-to-buy yarn bookmarks. They are just too mainstream. Your kid deserve something cooler than that. Why not attach a pompom on a popsicle stick? It is not very costly and a pompom is easier to find than a string. That scruffy thing will make your kid want to read a book in an instant.
