One thing that I saw was someone put different dollar amounts on different envelopes and each week they would put that dollar amount in the envelope (it could be $1, $5, $10, $20, etc). This helps to save money because it breaks up saving into smaller parts that are more manageable and can adjust to your needs. If you’re having a tight week with cash, you can fill the $1 envelope, and on the flip side, if you’re doing well, then you can fill the $20. Hope this helps!
