Has anyone ever made their own laundry detergent? [View All]

[Flaxbee]

I've seen recipes before in magazines like "Natural Home" (a good magazine, by the way) but have all of my magazines packed away (we're just living in our current home for a few more months) and wondered if anyone could give me a recipe they've used and actually liked and that got their clothes clean.

What kind of fragrance can I add -- is it OK to mix in a little sauna scented oil or something? I'd like to do something less expensive and much more environmentally conscious than the stuff at the regular grocery store. I like the idea of Seventh Generation's detergent but it's kinda expensive, though I do realize it's very concentrated and would last much longer than regular "Tide" or whatever.

Just fishing for ideas, if you have any they'd be appreciated!
