Confession time. I regularly employ magick along these lines. In fact, the very first spell I learned as a young teen with CoR, was glamour magick. I, however, don’t use it in regards to interpersonal relationships. Nope, I have ethical issues with that. I do use it for my career.
Glamour is not a guarantee to success and in of itself will fail without the proper display. Just remember that glamour makes the impression being given just a bit stronger. It does not bend, dominate, or control another’s Will under that impression. Though there are magickal practices that are designed for that, glamour is not one of them.
The cake in these instances is how one dresses, talks, and carries themselves. It is the face you put on for the world. The Witch, by use of glamour makes this face stronger. Say you are going to a job interview, no amount of glamour is going to help with the appearance of being a professional if one shows up for it in flip-flops, swimming trucks, and no shirt with the scent of whiskey about one. Crap cake that is. However, show up with the attitude and clothing to support, then the glamour will help to smooth out any rough bits.
The methods of glamour I employ come from Southern Conjure but can easily be adapted. Here is one, though with research many others can be found.
Start with a bath, a basin bath. The bath needs to have cleansing elements as well as properties that you wish to imbue. I’d give you a recipe but I think that’s cheating. Bathe before sunrise with an up-stroking motion. When you are done, drip dry. Can’t go rubbing the work off now can we? As the sun is coming up, go throw the basin water away from you over your shoulder towards the east. This is splashing the intent upon the day with the rising sun*.
What methods of glamour have you used?
"Lost in a thicket bare-footed upon a thorned path."
*Note: In conjure there are many ways of getting rid of bath water, this is one and not a very common one at that.
