Summarize:

You probably already have what you need to cover up your eyebrows around the house. Get everything ready before you get started. Here's what you need: A small bottle of spirit gum (sold at costume shops, and is made for use on the face) Petroleum jelly (e.g. Vaseline) Translucent concealer powder that matches the color of your skin Liquid concealer or foundation that matches the color of your skin Colour correcting concealer (optional) Apply the it in the direction of your hair growth, taking care to help each hair lie as flat as possible against your face. If you have thick eyebrows, you may want to wait another ten minutes and apply a third layer.
Gather supplies. Let the spirit gum dry for ten minutes, then apply another layer.
