What is a good makeshift way to roll out dough?

or roll it out on something flat, like a cookie sheet? when you find a good, flat surface, use two sheets of plastic wrap to roll out your dough.

Try putting it on a floured flat cutting board and using plastic cling wrap on top

Some options, none of which are perfect, would be: a non-terrycloth kitchen towel, parchment paper, wax paper, a brown paper bag. Also, you might use a cutting board or stacked newspapers to support underneath if the counters are bad. Good luck and Merry Christmas!
