Your Runes, Your Choice
If you make Runes for divination, you have many choices. My original sets were small sticks, about three inches long with a Rune carved on one side. There was a time I did not have Runes with me. In a pinch, I took stones from the beach, rinsed them, let them dry, and marked them with a marker. They worked just as well.
A friend made me a painted set of cherrywood. I also have one of shaped round chips. I had made it in a pinch, and it has served me for over 20 years. There are about ten Rune sets out that there I had made with shaped pieces of wood. Some are round, and for some I used heart-shaped chips that I had gotten. Each of these sets has the Runes marked over pictures I painted. For instance, the Ken Runes have lighthouses. Most of the painted sets were gifts.
I like to use the cherrywood Runes and the shaped round chips.
The point: there are not hard and fast rules for making your reading Runes. Choose a material and shape that appeals to you. Keep in mind that in a pinch, you can improvise. Your Runes, your choice.
