Before I discuss ways to make "proper" perfume here's an idea for an easy to make fragrance using only home ingredients.
Take about a cup and a half of flower blossoms. You can use rose, lavender, honeysuckle or anything that has a strong fragrance. Chop them roughly and add to three cups of warm water.
Leave the mixture to soak overnight and in the morning strain through cheesecloth or similar material. Put the mixture into an old saucepan (you may not want to use your best pans for this!) and simmer on the stove gently. The emphasis is on the word gently. Use only a very low heat. Reduce until there are only a few tablespoons left.
Cool and store in a suitable bottle. This fragrance will keep for about a month or six weeks in a cool place.
