While you are working on your projects keep the unused portion of the dough in a plastic bag. That will prevent it from drying. It is best to use up all the dough at once but if it has to be kept longer, refrigerate it in a plastic bag. 
 

Supplies: knife, a little water, extra flour, aluminum foil, garlic masher, paint brush

   Complex designs can be carried out with the simplest geometric shapes. If you roll a piece of dough between your hands (circular motion), you will get a ball. By squeezing the ball a "pancake" can be made. The pancake can be used to me make hats and other accessories. To get a sausage just roll a piece of dough on the table. If you do it just using hands it may not come out as even. If the dough seems and wet and sticky add more flour to the working surface.

   Connecting parts together: to connect a body and an arm, for example, slightly wet the spots to be connected on both pieces. That way they will not fall apart. You can also use toothpicks for extra support, but I have not found it necessary.

  To make bigger creations lighter and decrease the drying time, roll in pieces of foil in in the center of bigger parts.

A garlic masher can be used to make hair, for example. I used it to accent the clothing I formed out of dough.

On colors:
you can separate the dough in different parts and add acrylic paints. That way you will already have colored pieces to work with. The result turns out to be quite different than if you paint your creation after it has completely dried.

Some other supplies that may come in handy:
toothpicks, iron wire (make a loop and insert into top of figurine and it will become an ornament), rolling pin...

Once you are done constructing its time to put your creations in the oven.
