Recipe: (Double this recipe if you want it to last 2 years like it did for me :)

1 Box Borax
1 Container Oxi Clean (Regular Walmart size)
2 Bars Fels Naptha (Laundry aisle)
2 Boxes of Arm-n-Hammer Super Soda
1 Box Pure Baking Soda (this size box is only found in the laundry aisle - not the size you bake with)
2 Large Containers Downy Unstoppables (Any Scent)
Grate Fels Naptha bars completely, then put them in a food processor and pulse until they become a pea sized ball consistency. ***(Do not just blend - the grated fels naptha will simply cream together into one clump - NOT what you want for your laundry detergent).
Mix all ingredients in a very large tupperware tub or air tight container (makes alot)! (I like to double the batch, so I don't have to make it as often).
Use 1-2 Tablespoons per load of wash. ***Note: Always add water to your washer first, then the detergent, THEN your clothes. If you put your clothes in first and add the detergent on top, you will get detergent powder stuck in the wrinkles or pockets in your clothes. (I only know this from experience ;)
***I store mine in a 27 Qt. tupperware tub/container with a snap on lid.
***I doubled the batch and it has lasted me two full years! Think of how much you will save by making your own!!!
