Well, many, many other homeschoolers have helped me by reselling their curriculum at a greatly reduced rate from new.
A few weeks ago, my dh and my dad mounted a wall board for us to use for homeschooling next year. I don't do a lot of lecturing, but it is a great place for brainstorming or working out math problems. Even my now-graduated son is thrilled by it. I came down one morning and found it filled up with calculus problems. LOL
No kidding! LOL I did not homeschool my older three kids. Not only would I never have homeschooled without my youngest, but I would never have had a daughter or become a SAHM! She truly was a gift from God. I was 40 the year I had her and had given up on ever having a daughter. She has TOTALLY changed my life!
