After reading 8 pages of posts, I can't remember which one or two people mentioned it... But if you are going to buy already made runes, search about for something that "jumps" at you.. Something that feels comfortable, and as if it were a part of your own body. Commonly, runes are made from wooden branches, glass beads, sculpted clay, carved animal bone, or river pebbles. Perhaps you will find something that feels more appropriate to you. Maybe you'll even have to try out runes of various medias before you find one that you are most comfortable with. Personally, I prefer elder futhark runes, and I own two sets. Some other types of rune scripts are:  Younger futhark, Frisian futhark, fairy, and Ogham. Traditionally, Ogham runes are carved from wood. Experimentally, I tried making a couple of different sets from glass aquarium beads (I tried clear, light green, blue, and a "wine" colored) but none of them felt right. The markings were painted with a golden paint marker. These never felt quite right to me. However, what feels wrong to me may be just perfect to you.

My second set was a purchased set, gifted to me from my best friend and lover. That set, too, bears Elder futhark markings. The set is a mixture of large, light and dark river stones, painted with gold marker paint. I got them when I first began learning about runes. These work best to me, as they  are unpolished stones, smoothed over by water before I owned them. Water is my element. I feel that I have bonded with them. I raise power, cleanse, and ground power before and after each time that I use them, or each reading if I am going to do a few in the same sitting.

I hope that is of help to some of you.

Best wishes!

I make my own, from natural materials such as wood and acid-free paper. Ones I make myself I've dedicated to just using for my own personal readings.
