In the past we would buy this size notebook at the dollar store, but we could have gotten multiples for the same price at Kmart! What a great deal! The covers come in various colors so it's easy to ID which notebook is for which subject if you're using for school. Or, for home use, it's also super useful to tell which color belongs to who in the household. We are using ours to log feeding and diaper activity for our newborn baby. I bought a few more notebooks to use for other projects as well. My husband uses them for his DIY plans to sketch and project, write down dimensions, and make a shopping list for the hardware store. I use them for sewing projects and other creative ideas. It is really handy to be able to have a notebook for each topic. Keeps you organized!
