Thank you to MTS also....I got half the idea from her then finished it off.

The top and bottom don't necessarily need to be aligned, but the sides DEFINITELY do.
Like she said...the degree of the angles don't matter as much.
You COULD do lines from 2" to 10" for a flatter diamond, or 2" to 14" for a higher pointed diamond. But the concept is the same.

Thanks again MTS !!!!!!!!
