The Divide-It cash envelope system wallet is sold on Etsy for only $21.50 (at the time of this article) and comes with six blank tabbed category dividers. You can choose from a huge selection of fabric designs. This shop also sells custom labels for the dividers, spending logs that fit in the wallet, and coin and card pouches that fit inside the wallet; these are old sold separately from the wallet.
I started using Thirty-One throughout our time in Italy. I used the bags to keep our small apartment organized and I especially used them when we traveled. I quickly realized that a Large Utility Tote was indispensable when we traveled. I used one in the back of the van for snacks, drinks, trash bags, and food (since we exclusively stayed in Airbnb homes). I realized that using multiple Zipper Pouches was a more efficient idea than having Ziplocs in my mom bag. https://i.pinimg.com/236x/76/aa/ed/76aaedb660282c49c58f7dcc3921e793.jpg
