Make-it-yourself laundry soap?

I've been wanting to try making my own laundry soap for awhile, but I am so skeptical if it really works.  With a husband that gets dirty at work.  A teenage boy that plays football and does weight lifting (EWE) it has to clean good!  I'm sure you all can imagine.  And how will it smell??  With a husband who's super power is his sense of smell... if he doesn't like the way his clothes smell, they end up back in the laundry basket (or on the ground next to the hamper).  But today I found this blog and she talks about how important smell is also.  So, I think after this bottle of Tide is done I will give it a shot.  I mean really, who DOESN'T want to save money!  And laundry soap is EXPENSIVE!
I'll be posting my review in a couple weeks... I will need to pick up the supplies this week and have to give it a go.  I'm already nervous and I haven't even started!
Wish me luck!
