In this case; the word mattered more than whole. We'll call this bit part A]
A] If it were a "Name" then you would only make a design to incorporate the whole name and in the end you could make out the name in the design. This was meant to be a universal language, something that came before language. My thought process then became strip each word to its core, remove its prefix/suffix or sexual inclination. Find the core definition or if it had a Latin root and remember if it is intended for a spell what is the spell supposed to be use for, like why "Block/Deflect" has two definitions, because the root is deflect but since it's not the more common phrase I also added the word "Block" so people can relate "Ah, it's like a shield. That makes sense because it looks a bit like a shield."
Everything after that came down to more of a science. Pick the phrase, find a single word to simplify the phrase, strip the word to its core, apply/compare different runic samples from different cultures.
That last bit is where it turns to wholly different step but I would make sure to separate them entirely. Like make the list of maybe 40-90 commands, pick 25 I really attached to, translate those. That might take a few days. Then I would move onto the design part.
B] I used these really great and old-timey easily accessibly references;
I combined their defining characteristics into one glyph in my own handwriting, or more accurate calligraphic "stroke". I think I described this best on a bar napkin and uploaded it to my tumblr.
THIS is not how I would approach every design project but Cassie's was so particular and we discussed it so many time/ways.
C] I should point out I had a lot of artistic license. Out of the 25 word/glyph/runes that I'd decided on using I would end up making maybe 3 variations. Sometimes if I really got Obsessive Compulsive it got as high as 8. 10-18 glyphs would make it to Cassie with 1 or 2 Variations. I made sure she got my finest and favorites so I could live with what would eventually be circulated. She would whittle it down to maybe 12 runes over all. That would be one set.
The process would start all over again for the second set a few years later, only I decided to go much bigger. Much much bigger. This is how we came down to a set twice as big. You can imagine how much I must love the process and how much a mess my desk was for the months it took.
I've done different designs, with different types of glyphs for different project and never repeated this process because each project really does demand a different aesthetic.
I would not recommend this process. I am a maniac who loves homework.
This is a lot of info for one reply which is why I procrastinated replying, not because I forgot, but because I really wanted to delve into and not I apologizes for you having to get this far, if you got this far, that I totally love you for it
To me it doesn't matter about giving away process since it's not exactly like process can be exactly repeated even if it can be learned. Everything is derivative of something but there's even art in that.
William S. Borough said "Art belongs to the living artist" - "Steal everything" which there is room for argument over, since he didn't exactly mean directly but you get what I mean
I hope this helps. Thanks for the question and the interest
