Find and stage the ingredients: Peanut butter, jelly of some kind, bread. You may need to run to the store. If so, I’ll wait right here.
Grab a couple essential utensils: Small plate, broad dull knife.
If your bread’s sliced, pull out two pieces. If it’s not, cut two slices. Find your bread knife, your dull one won’t cut it.
Lay one piece of bread on the plate or your work surface. Open the peanut butter jar, scoop out an appropriate amount of peanut butter, to your liking, spread it onto the bread. The proper amount is up to you, but I’d recommend creating a layer no more than a quarter-inch thick, and don’t get too close to the edges of the bread. I recommend starting with the peanut butter. It’s denser and thicker than the jelly, usually, and provides a good backing to the lighter jelly. But you can switch the sequence around and see how it works.
Then go to your jelly jar, scoop out some jelly, again to your taste, spread it on top of the peanut butter. Again, the amount’s up to you. I personally like a neat sandwich and don’t overdo the adding of ingredients. A good sandwich has a balance of bread and the sandwiched materials.
Peanut butter and jelly sandwiches don’t often get too thick, the way lots of other sandwich assemblies do, so that’s not much of a problem. If you’re really hungry, you might make a thick sandwich and rush to the eating stage. If you’re just regular hungry and can hold off a minute, make two sandwiches, one after the other. To me, this approach is better, as a too-thick sandwich made from liquid ingredients can escape your mouth when you bite down, making a mess.
Close the jars. If you’re a neatnik and don’t plan on making another such sandwich soon, clean and put away the knives, brush any breadcrumbs or stray ingredients off the counter. Put away the jars of peanut butter and jelly and your loaf of bread.
Back to the sandwich: Put the unspread-upon bread slice on top of the spread-upon one, press down slightly to get the jelly to adhere the top slice to the bottom slice.
It’s done, your sandwich is made, Enjoy!

This is the first exercise in John Warner’s book The Writer’s Practice. He asks the reader to do it, right off the bat on the first page. His explanation of why he did this included these ideas–we’re all writers, we can improve our writing practice by doing, we must always consider the audience we’re writing for, and we can and should approach any writing task as a writing experience, more than a mere task.
