I have Blum's book and runes ... SOMEWHERE, my daughter got a hold of them when she was little. I've made two sets, one from flat river stones that I got from an amazing woman who was a lapidarist and had the MOST amazing assortment of crystals in her home. I also made a set from sculpy. All three sets worked well for me. Haven't used them in decades though.

The runes work a lot like tarot cards, in that there is an upright and reverse (upside down) meaning. I went by Blum's book for definition and it was quite accurate for me anyway. I even had a vanity plate once with one of the rune's name Eihwaz which symbolizes growth. Always got asked about it too.
