I followed the advice on this page
http://www.io.com/~sjohn/sour.htm
but I mixed in some freshly ground flour from my own grown wheat, barley and oats reckoning that it would be the right yeasts and a small handful of dried elderflowers.....kind of because it seeemed a good idea at the time
it seems to be working just fine, smells great, makes excellent bread, even with the wholemeal stone ground coarse stuff the kids managed on the saddle quern.
There's another site that had good info too,

It's really pretty straightforward, the starter lives in a big pickle jar in the fridge and I feed it every three or four days, though I have left it a week and it seems to be fine.
My sons keep making comments about *Audrey* for some reason
