On April 2, 2010, the hubby and I made laundry detergent (you can see the directions and pics of us doing that HERE)...we are down to our last half gallon so we had to make more today.
I quite enjoy only having to purchase laundry detergent twice a year (well about that anyway) and Kevin figured it out that it only costs us about $4 and some change to make 10 gallons. That does not include the bucket which we bought for about $5 and is reusable. So less than $5 for laundry detergent every few months is not a bad deal!!
