I started with the fabric folded in half to get the length.
In hindsight, I could have taken it a bit shorter but I knew I wanted the skirt to sit on my waist and it is always better a wee bit long than a wee bit short!
I folded over a nice wide waistband to thread the elastic through.
It took no time at all to make up, I think I was done in about an hour and it looks great.
Here is it teamed with my New Rock boots and black tights.
