Drawing Saint Peter's Cross

St. Peter's Cross is simply a Latin Cross drawn upside down. To draw one you can work it out from the Latin Cross tutorial or just follow the steps below.

For a quick and easy method, use a grid and follow this pattern:

An example of making this cross using a grid

If you're not using a grid, here's a simple technique:
Draw a vertical line where the stipe goes. If the cross is resting on something, start from the bottom and draw upwards. Note that this particular line needs to be as straight as you can get it.
Place a mark in the center of the line, then the center of the bottom half, and the center of the bottom half again.
The smallest segment lets you know how wide the stipe needs to be; add the top and bottom of the stipe by drawing it on the ends of your line.
Connect the ends of the stipe and we'll be ready to move on to the crossbeam.
Draw a horizontal line across the second mark. This will form the bottom of the crossbeam, so it should be twice the width of the stipe, not counting the area inside the stipe itself.
Add the sides of the crossbeam by drawing lines going up from the ends of the last line you drew. These lines should be as long as the stipe is wide.
Connect the lines to finish the crossbeam
And you're done!
