While not an essential skill, the making of ink will certainly come in handy if you happen to have a quill!
I am only going to lay out a few basic recipes here, though any of these will work perfectly well.
For the first one you will need 1 tsp of gum arabic, 4 tsp. of tea (or about 4 teabags), and 1/2 cup of boiling water. Pour the boiling water over the tea and the gum arabic, steep, and then squeeze all of the extra moisture out of the tea. Strain and let cool, and then you have a very simple ink.
The next is a little bit more complicated, though still simple. You will need walnuts, water, salt, vinegar, and a cheesecloth. First you must crush the walnuts. Then pour water over the crushed walnuts in a sauce pan and bring to a boil. Once the mixture cools, pour it into a clean jar or other container, using the cheesecloth as a strainer, and mix in some salt and vinegar. There you have it, another recipe for ink!
For other ways to make ink, you may use a variety of berries and fruits. You may even use the seeds of fruits, such as pomegranate seeds, which will make your ink a rusty colored red. To make ink with berries, use your judgement. Does the berry tend to stain clothing? If so, you probably have a good candidate for an ink. Make sure you add salt and vinegar to whatever berry or fruit you use. They will act as a preservative and help to keep your ink long lasting.
