If you aren't a nut about shape, pat the kneaded dough into a rectangle and cut squares with a floured Ginsu knife. Untraditional shape, but nothing wasted.
That was on the documentary too!!! It was at a breakfast restaurant in Nashville, TN and they dropped a huge blob of drop biscuit dough on a cookie sheet and used a scraper to cut it into squares. If you can see that documentary, I think you would enjoy it. There was alot of history in it about the South.
Check out the Flying Biscuit Cafe biscuits. They rise to almost 6 inches sometimes. yummmmmmmmm!!!!!!!
