I feel the need to be honest about our money situation. It might look like I buy lots fabric, sewing, and crafting supplies while claiming to be poor students. I do buy stuff, but it's money from "my budget." My budget money is from doing alterations and tailoring work. Once people find I can do tailoring and alterations, they always ask me to do things for them. I almost always charge because I don't have time to do work for free. (And neither do you!) My husband and I decided that anything I earn from alteration work goes into "my budget." Like last year I did some big projects like a wedding dress and another wedding dress so I've been saving up for our time in law school.
Besides doing a couple hours of online work a week I feel that staying at home helps us save money because we don't have to pay for childcare, and I'm doing my best to learn to run a frugal household. I'm grateful for Pinterest which helps me find frugal recipes, homemade laundry soap recipes, homemade cleaner recipes, etc. Also, I'm a much happier person to be around when I don't have to work a full-time job.
One problem with being in school is the expensive textbooks. One trick we just found for my husband is getting his books from Campus Book Rentals. The books are 40-90% cheaper than bookstore prices, and there is free shipping both ways. They also donate to Operation Smile with each textbook rented!. It's a great way to get my husband his books for a better price. I really wish I would've known about renting textbooks while I was still in school, like my favorite class and book, Survey of Historic Costume 5th Edition. I did end up keeping that book, but renting books for my generals classes would have been great.
