Not sure what sigil creation method you are using. Here’s
some advice for the basic letter sigil method.
Once you have your letters, try drawing them holding your
pen at the top instead of the base, with your eyes closed. This will help you
tap into autonomic writing, and get some more interesting shaped letters. Don’t
be afraid to modify or discard shapes as per your intuition.
Once you have your sigil drawn there are multiple ways to
charge it. I find this is where most people half-ass it, but it’s really the
most important part. Since you follow Thelema, performing a Greater Ritual of
the Hexagram invoking Jupiter would be good.
Some sigils you destroy in order to launch them, some you do
not. In this case, I would place the sigil on something your significant other
can carry with them. Once you make the sigil-object for them, place it in a
safe place, an actual safe would be best, but anywhere you would stash
something valuable would work. Also, draw the sigil somewhere you will see it
often, even on your hand. Every time you see the sigil, think of your SO
returning safe.
When it is time for them to leave, give them the
sigil-object and erase all traces of it at home.
Hope that helps.
