I want to recommend a few posts I've read very recently that I thought quite wonderful or helpful.
Visit Women not Dabbling in Normal to read Robbyn's (from The Back Forty) post 'what would Gramma do?' It's a wonderful read as she reminisces about her grandmothers lessons in making do.
If you are considering (or wishing for) a wood burning cook stove you do not want to miss Granny Miller's post on Cook Stove Basics.
And last of all, for a great synopsis on rechargeable batteries head on over to Planetary Verbosity.
This is why I so love cyberspace. There is such a wealth of information at our very fingertips to educate and enlighten us.
