I recently went through some of my recipes and created a new binder for some of the more used baking recipes that I printed off and didn't put on index cards.
I made this cover for my binder and the spine. I have seen some pretty cute ideas out there and some free printables for binder covers like this one over at Prudent Baby
I filled my binder with clear sheet protectors that I can slip new recipes into as I come across them. These sheet protectors are not only a quick and easy way to organize but will also keep my recipes clean when I am using them
