Step 1 (below): Start with a 2" styrofoam and same size fondant, put the ball inside. Make it look sort of an apple: wider on top, narrowed on lower part.
Step 2 (below): Use your finger or a small rolling pin to mark on the face where the eyes will be and to make the cheeks.
Step 3 (below): Use the rolling pin to smooth out the face.
Step 4 (below): The distance for the forehead should be wider, so you can have enough room for the hair or the hat.
Step 5 (below): For this step, you can use any of your piping tips - I used the round tip #10 and #12 for making the eyes.
Cut a little corner of your tiny circle so you can add a side detail on the doll's eye
Step 6 (below): For the rest of detail, just make a tiny sausage and thin the sides and add the eye lashes. Cut little green circle for the iris and the shine on the eyes.
Add the mouth, and 2 tiny round circles using round tip #10 . Tip: When ever I do not have the right round size I need - I roll my fondant thicker cut the circle and press it gently in between my fingers so it can be bigger.
Step 7 (below): Use a large heart cutter to to cut the shape of the hat or hood that she wears.
Use a large circle cutter (4" 1/2 at least) to cut a circle to add it to the witch head. Most of the time I roll the fondant thicker so I can have more chance to smooth it thinner and cover all of the head.
Step 8 (below): Make a sausage with thin ends - cut in half to make the horns.
Shape inside then outside like an "S"
Step 9 (below): Next add half toothpick on the sides of the head, like where you would add some piggy tails.
Glue the horns and add purple details using an extruder.
Step 10 (below): On the styrofoam cone, add a pice of flower wire. Glue it to the styrofoam so it doesn't move.
Cut a purple strip and add to the bottom trying to ruffle it a bit. Best way to stick is by using a bit of shortening directly on the fondant. Add a wooden skewer just on the top of the cone all the way through the cone.
Tip: Styrofoam never ever should touch the cake surface, add a piece of fondant on the bottom of the styrofoam piece.
Step 11 (below): Cut a large circle to cover the body & put it on top as you are putting a shirt. Cut the sides where the fondant meets the wire and hide on the sides and smooth. Cut 2 purple stripes about 1/2" wide for the dress details on the front
Step 12 (below): Cut a small circle and and add and irregular stripe to the circle, you can use a special cutter or use your imagination to make it look irregular. Fold the circle over the wire so you can make the arms.
Add some disco dust to make it more dramatic. . .
