To curl your lashes with a spoon, follow these steps:

1. Heat a teaspoon in a glass of warm water for 3 minutes. Fill a glass halfway with warm water, and place the clean metal teaspoon in head-down. Leave the spoon to heat up for 3 minutes.

2. Dry the spoon. Remove the spoon from the water and dry it with a clean cloth. Wet lashes wont form or hold a curl well.

3. Hold the inside of the spoon over your eyelid. Hold the spoon horizontally and press the inside of the curve against your eyelid. The rounded outside face of the spoon will be used to curl your lashes.

4. Press the top lashes against the spoon for 10 seconds. Pull the top lashes back against the curve of the spoon using your fingertips. Hold the base of the top lashes against the outside face of the spoon for 10 seconds to help set the curls. The curve of the heated spoon will help to set the top lashes into a curled position.

5. Sweep the mascara from the bottom to the top of your lashes. Stand in front of a mirror and look straight ahead. Bring the mascara wand to the base of your lashes and wiggle it back and forth as you move it up your lashes.

As for product details, there are no specific products needed to curl your lashes with a spoon. You only need a clean metal teaspoon and your favorite mascara to set the curls in place. There are no positive or negative aspects to using a spoon to curl your lashes, as it is simply an alternative method to using an eyelash curler.
