Cajun Spice Seasoning Mix in a Jar

3/4 cup salt
1/4 cup ground cayenne pepper
2 tablespoons ground white pepper
2 tablespoons ground black pepper
2 tablespoons paprika
2 tablespoons onion powder
2 tablespoons garlic powder

While holding a pint canning jar at an angle, add ingredients to create a "sand art" look. The salt and cayenne may be divided into smaller portions and used to separate other spices. It is simplest to use 7 cups--one with each spice in it--and add them to my jar with a spoon, as I want to create the special look.
