Calculation of the material requirement
Measure the waist circumference and multiply by four (for example, 50cm x 4 = 200cm), this results in a cape for the skirt. You need four layers for younger children and six layers for older children.
An example: the child in our instructions has a waist circumference of around 50 centimeters
50cm x 4 = 200cm200cm x 4 layers = 8 meters
You can count on about eight meters for small children and about 12 meters for big children and adults.
