One solid modern tradition is to create sigils to focus the energies into a particular intention by arranging the letters (or letter shapes, omitting those that repeat) into a sigil.
Here, I’ve made some of those based on the named of four deities. The intention is that these should be used in addition to other techniques to help deities to manifest.
Paint them on the base of your icons, or onto banners that you hang on the wall.
Salted paint works well.
