As newlyweds, my wife and I really wanted a recipe book so we could start compiling and creating our shared collection of favorite meal and dish recipes. But I was worried that we'd run out of room in a standard book and need to get another one eventually, so I opted to surprise her with this lovely Sage Green Recipe Binder. The sleeves fit the 4x6 cards and you can fit everything you need on the double-sided cards (which have lots of directions and extra notes room on the reverse side). The color is attractive, the metal corner covers were all sturdy, and I really appreciate the overall aesthetic, simplicity, and beauty of the book. I think it's awesome that you can just buy more cards and sleeves when they all fill up, and it'll keep all the recipes in one neat place!Note that you will need to rewrite the recipes on these cards, as the sleeves are made to fit the cards, not full sheets of paper. If you're ok with that, or have smaller index cards, they should fit nicely. But overall, extremely satisfied with the purchase and would highly recommend!
