For at least a month, try the basically-free method of using standard white mailing envelopes (or any of the other cheap DIY cash envelope organizers). Label each envelope with a budget category, stuff them with cash, and put them in your purse. If you stick to this system for a month or more, and find that it is helping you curb your spending and stay within budget, then invest in a special cash envelope wallet.
I noticed in the catalog that you could fit files in the zipper pouch (it was a lot bigger than the pencil pouch I was picturing), this made me rethink my current “office in a bag” for finances. I placed three files in the zipper pouch: “To File”, “To Handle”, and “Stamps and Envelopes”, then I placed my check book, my budget notebook and my extended budget (which is in a cardboard file) inside the pouch. I am so excited about this set up! It reduced weight and bulk and secures the files while letting them remain upright. It's a huge benefit to me to have all of our budgeting tools with me at all times. I can pay bills, track purchases and adjust the budget in little breaks throughout the day omitting the need for a set time, that I sit down and balance the budget. https://i.pinimg.com/236x/2e/f4/72/2ef4720f113622d1a6044a8361c35a66.jpg
She looks for wool and flax, and works with willing hands. She is like ships that trade. She brings her food from far away. She rises while it is still night and makes food for all those in her house. She gives work for the young women to do. She gives careful thought to a field and buys it. She plants grape-vines from what she has earned. Proverbs 31:13-16 https://i.pinimg.com/236x/c8/ef/72/c8ef72904a6ff42c6d2688928e6e389a.jpg
