Yardage chart bias cut skirt?

[Nerys]

Does it exist, a yardage chart on how many metres/yards to buy for bias cut skirt?

[BrendaP]

There are so many variables there, it's not really feasible to put that sort of thing into a chart:
Fabric width
Skirt size
Hem circumference
Skirt style (straight, A line, pleats, several panels ... )
Waistband style (or absence)
Pattern matching

The best I could suggest is to find something similar which is designed to be cut on the bias and go with the reccomended yardage for that.
