Lay in a tub full of warm water. While in the water run your fingers up and down your legs saying the following spell:
These short legs, become long;
Sleek and slender don't go wrong;
From toe to hip my legs will grow,
And be a wonder I must show
To all who wish to see such beauty,
For from now on I'll be a cutie.
This spell should be cast weekly, or whenever you happen to be in the bath.
