The process involves arranging them into ways that look good, before mirroring it to make it symmetrical
This one, ring, is used for the schiltrom formation. I put them against a backdrop.
They aren't perfect, but unless Brandon Sanderson releases several glyphs for things that aren't at all important to the plot, than they are all we have. Some others that I made are:
The above are: Fire, Shoot, Pike, Walk, Wedge, and Tight. There are several others, but you can play and find out about some of them
