I know I said this in my 72-Hour (Semi) Sourdough Bread post: Making a sourdough starter is straightforward enough, but unless you're making a loaf or two every week, keeping a sourdough starter going is more trouble than keeping a cat!
Since then, I've decided to give it another go. It's been many years since I had a sourdough starter living in my kitchen for any length of time, and I guess the cat wasn't keeping me busy enough, so ...
But you know what? It really isn't that much trouble!
You can make your own sourdough starter using nothing but equal weights of organic unbleached all-purpose flour and filtered water. You can do this with measuring cups, but a digital scale is a must if you're a stickler for accuracy.
With a digital scale it is a simple matter to just set the bowl on the scale, press the Zero button to temporarily set the scale to zero, spoon in flour until it registers so many grams or ounces, press the Zero button again and then pour in water until it registers the same number of grams or ounces on the scale.
But if you don't have a digital scale and don't plan to get one, you can make a sourdough starter just fine with your measuring cups and spoons. Just pick a measuring method, cups and spoons, ounces or grams, and stay with it throughout.
I'm no expert on sourdough, but one thing I've learned is that sourdough is more art than science. So I'm more inclined to go with those experts who wing it a bit than with those who insist on precise measurements.
Start with maybe 2 tablespoons of flour and 1 1/2 tablespoons of water (roughly equal in weight). If using a scale and going by ounces, start with maybe 1/2 or 3/4 ounce of each. If going by grams, maybe 15 grams of each.
Tip: For the same reason I recommend making the starter in a 2-cup glass measure (so you can easily tell how much it has risen), I like to use a 2-quart glass measure for the dough when making Sourdough Sandwich Bread or other not-too-large recipes.

You should start with a very small amount of flour and water because at a certain point you'll be discarding* some of the starter. If you're using large amounts, you'll be wasting a lot of flour. Of course, rather than throwing it in the trash you could compost it or even use it in a recipe such as sourdough pancakes.
* But with my method you'll be discarding far less of the starter initially and none at all throughout the years you're using it!
Your starter might be "ready" in one week, or it might take 2 weeks or more. So plan on babysitting your starter for at least 2 weeks. It will continue to develop flavor and strength, some say for another 30 to 90 days.
Since this will be on the counter for a week or two, pick a spot where it won't be in the way and where the temperature will be fairly consistent (70 to 75 degrees would be ideal). Pick a time of day that will suit your schedule; you'll need to feed your starter about the same time every day.
If you use a straight-sided clear container, it's very easy to watch your starter's progress. A wide-mouth pint glass jar is fine, but I found I prefer a 2-cup glass measure. Then I store the starter in the jar with a square of plastic wrap held in place by a loose canning ring.
You'll find people who tell you to use grapes, cabbage leaves, pineapple juice, certain grains of one sort or another, or even milk to make your starter. Some people say you cannot make it in a metal container or even use a metal spoon. Some people insist you must use a scale and be very precise.
I'm not saying those things don't work. If that's how you make and maintain a sourdough starter, stay with it. But if you're new to the game, I'd say try it this way first. Sourdough starter really isn't all that fussy. I use organic unbleached all-purpose flour and filtered tap water.

Sourdough Starter
Organic unbleached all-purpose flour
Filtered water
Day 1 In glass or ceramic 1-pint container, stir 2 tablespoons flour and 1 1/2 tablespoons water until smooth. Cover loosely with plastic wrap or a slightly ajar lid. Or 1/2 ounce or 15 grams of each.
Day 2 You may or may not see a few bubbles in your starter. Feed the starter same amounts; stir vigorously until smooth. Cover loosely with plastic wrap or slightly ajar lid.
Day 3 You will probably be seeing some bubbles now, and the starter will be smelling a little sour. Feed the starter again, just as on Day 2.
Day 4 The starter should be very bubbly and may have doubled in volume at some point, and it should be smelling quite sour. Also, it should be looser in consistency. Feed the starter again, just as on Days 2 and 3.
Tip: The speed at which sourdough starter develops depends on many things. My latest batch of starter did not double until Day 12.
Day 5 The starter should be frothy and may have doubled again since yesterday. It should smell even more sour and be even looser in consistency. This time, discard all but 1/4 cup starter and feed it with 1/4 cup flour and 3 tablespoons water. Or 2 ounces or 60 grams and feed it with 2 ounces or 60 grams each flour and water.
Tip: At some point in the process, your starter may start smelling like acetone (nail polish remover); don't be alarmed, just carry on. Or it may develop a layer of liquid ("hooch") on top; just stir it in and carry on.
Day 6 Discard all but 1/4 cup of the starter and feed it with 1/4 cup flour and 3 tablespoons water. Or 2 ounces or 60 grams and feed it with 2 ounces or 60 grams each flour and water.
Day 7 Repeat as on Day 6.
Day 8 Sourdough starter is ready to use when it is both one week old and doubling in size between feedings. On Day 8 it will be one week old, but if it is not doubling, just be patient and keep going! It may take 2 weeks. Keep discarding and feeding.
Tip: At this rate of feeding, after one week you will have at least a cup of starter--enough for a recipe and to hold back 1 ounce of starter to store and build up again for a recipe. If it's not ready, though, you'll want to proceed with a reduced amount of starter to be fed with equal weights of flour and water until it can double itself between feedings.
Update 10/28/17: I've kept my little batch of starter in a little half-pint jar (no discarding ever) since 2014.

Using and Maintaining Your Sourdough Starter
Cover it and refrigerate. Get into the habit of taking the starter out and feeding it once a week, letting it sit out overnight before returning it to the refrigerator. It will continue to develop flavor and strength, some say for another 30 to 90 days.
