Cut the circle into 12 wedges. Roll each wedge, beginning with the wide end, and shape into a crescent. The point of the wedge should be tucked under the roll. (See this video for a demonstration, but note that you should cut the dough into 12 instead of 8 wedges: https://www.youtube.com/watch?v=WAgAIe2b-mY)
Place crescents on a buttered baking sheet.
