To shape little stars out of dough is very easy. I made some picture for a little “How to..”.

Shape the dough to balls. Now flatten the balls and make a cut in the middle of the dough with a knife or a credit card. Rotate the card 1/3 and cut again, repeat it for a third time, leaving six points in the middle (see picture). Turn the dough inside out, so the points are now outside, forming a star.
