I was going to create a detailed thread about this as part of the shaper system involving Names & faces.
There is more to it then I’ve explained below. But I’m hoping it would give you some help to start with.
Use a letter shape if it ends with “a”.
Here is an example of how Anna and Gina might look like.
Ann = Hand (assign an action. it might slap the face, draw on the face etc. )
A = Geometric compass (Letter shape that looks like A)
Ann-a
Hand holding a Geometric compass, and draws/uses on the face of Anna.
Gin = Bottle of Gin (Pour over the head, or any spot you choose on the face)
A = Peg (a secondary Letter shape, but you can still use the Geometric compass)
Gin-a
Bottle of Gin poured over the head of Gina while her nose is Pegged with a Peg.
Bottle of Gin poured over the face of Gina while her nose is wearing a Geometric compass.
in-a = This suggests it’s inside of something
So I would choose some large item that the person head/face/body can fit in.
Let’s say we choose “A Huge Empty Glass Bottle” to represent “in-a”
Attach the name image to the suffix image.
G = Ear (Letter shape that looks like an Ear)
Gina = G in-a = Gina is in a Glass Bottle that has a huge Ear.
in-a (inside)
Angel = Angel Wings
Angel-in-a = Angelina is " in a " ** “Glass Bottle” that has " Wings "**.
So each time you see ina (in-a), the person, or face/head will be placed inside the bottle.
And the image for the name will be either attached, or used as an action applied to the person or the bottle.
The method is to choose an image for each suffix, and reuse them if an when it ends with it.
Try it. Test it with a good few names & faces. And see how well it works for you.
