Using a Grid cube to map your turnarounds

If you get stuck - Go back to your Foundation - 

If you can't seem to draw your character's pose turning in space - simplify it to something you CAN turn in space - like a cube.

Use a Cube to map out where your character's limbs are relative to each other. imagine a sculpture on a block of wood.  have the block of wood just barely fit the dimensions of whatever you are mapping (feet, trailing cloth, elbows, limbs etc.)  use half way marks (or 1/4, or 1/3 ... as many as you like) to give you more landmarks.
Next, map the surface area and where your feet will rest on that cube.  Its easiest if you map these into corners, or touching at least an edge of the cube.

Now draw a cube in perspective over your drawing - you can start with your favorite drawing - the one you want to match all of your other drawings to.  draw your midway marks.  now map out where your character's Limbs should be relative to the map you just drew. 

FEET- Stance

•  you can even make a smaller mark for where the bone connects into the large shape of the foot - then it is even easier to literally "connect the dots"
• Take surface area into mind.  If your character is on his toes on one foot, or has a peg leg, map a smaller area than his flat foot.

Map out how his feet would fall on a cube. in this example I have made them just fit in the corners.  his R foot just crosses the middle line.  his back foot Left seems to be on his toes.  it does not cross the middle line.  now I turn this cube in space.  draw the middle lines and map out where his feet will land.

Keep turning that cube in space.  by using this mapping method you will ensure that your points on the map are always  in correct relation one to another and will also help you see how extreme your perspective may be.

Grid Cubes can also be used to figure out perspective on a costume,

Limbs away from the body
Grid Cubes can be place anywhere on the character to map out a limb relative to another

Knees for example

Here is an example of mapping where 2 elbows are, relative to the shoulders.
