Polymer clay remains workable until cured generally from between 265 F (129 C) to 275 F (135 C) for 15 minutes per 1/4 inches (6.4 mm) of thickness. This temperature is significantly less than for mineral clays and can be achieved using a home oven. The clay shrinks inconsequentially when cured, about 12%. Brands of polymer clay include Fimo, Sculpey, Cernit, Formello, Modello, and Kato Polyclay. Follow individual package instructions.
I like to turn the oven on at low. Let it heat up for 5 minutes, turn it off, but leave the clay items in for another 20 minutes. Hard but not overly hard. It's also aadvisable to get your clay off while it's still hot, as the peices (if you have rolled and cut on the same surface you are bakeing on) will stick when cold... Really stick!
A home pasta-making machine is a popular multi-purpose tool for polymer clay artists. It is used to create sheets of uniform thickness (if you are a bit cheap, like me, you can use two peices of 1/4 inch doll rod. Clay in between... rolling pin will roll across the doll rods leaving your clay a 1/4 inch thich and snmooth.), to mix colors or created variegated sheets, and to condition (soften) the clay. Polymer clay generally needs to be conditioned prior to use. This involves kneading the clay by hand, passing it between two rollers, or using a low-shear mixer to break up any resin particle adhesions. Once conditioned, the clay will remain pliable until the particles eventually re-adhere.

Instructions
1 Start with small projects at first to get a feel for working with this medium.
2 Wash your hands and dry them well. The oil from the clay will really burn if you rub your eyes. I do a lot of crying when I don't think.
3 Lay a slab of clay or two for conditioning. I keep 2 slabs in a gallon bag. Before conditioning, I sit on it... You know, just lay the bag of clay under your legg while watching TV or whatever. You can not warm polymer clay, but you can use the radiating body heat to bring the clay to body temperature. Makes it easier to do the next step.
4 Knead the clay until it's smooth and pliable.
5 Shape the clay into whatever form you have in mind. (off hand I'd say use one of our molds.)
6 Use a wire frame inside the sculpture if it will have appendages or the piece is large. Polymer clay is limited in its support strength.
7 Make a bead by rolling a ball between your palms. Carefully poke a hole through the middle with a needle.
8 String beads on a wire stretched between two soda cans to keep from getting a flat side while baking. You may need to put some water in the cans for stability.
9 Bake the object according to the manufacturer's recommendations. Polymers take between 15 and 45 minutes depending on the thickness, and different brands require different temperatures.
10 Use an oven thermometer to prevent over or under-baking.
11 Wait for the piece to cool before sanding and painting. Use acrylic paints.

Most molds will stick to clay and distort the design when the clay is pulled from the mold, practice makes perfect. But, you can avoid the clay sticking to the mold by using a mold release: water; the simplest solution, talcum powder or corn starch. A small paint brush to dust the mold works fine. Work it a little, remove clay piece and re-dust. If your clay still distorts when you pull it free of the mold, try chilling the mold and clay for a few minutes in your freezer. It will make the clay stiffer and help avoid distortion. Wiggling helps a little. Mostly practice. Push the clay into the mold, filling it from the center out. Spread the clay to the edge of the impression, not beyond it. Some clay should extend a little above the upper edge of your mold.
