Thanks for all the info, educo
What you say at the end, sounds like batik
Anyway it seems like an intensive process...
I don't know if I'd really need to do all this work, and as you said, wax doesn't really give a shine.
This brings me to my research that I've been doing for the past month actually
I've been testing different ways of creating shine for fabric (by hand)
I've used several 'chemicals', like this gloss medium you've mentioned
Among making a sparkle, it also adds stiffness
I've also tried acrylic latex, PVA (white glue)...
It's all based on the connection between glues, resin, gums, varnish, etc.
They all have a similar idea: liquid form turns solid/stiff (and also shiny)
And all of them can be used in similar ways, like PVA glue can be used as a varnish for papier-mache, and so on.
In China, there is a group called Miao and they use egg-white to add shine to their cotton cloth --my instructor brought in a piece, it's wonderful! It's so stiff and shiny ..feels just like paper
Here's an idea of what it looks like-->

I tried this myself... My first test was not good because I didn't burnish the cloth after applying the egg. Two classmates did a research project on the Miao and created the same kind of cloth, and dyeing it with indigo. It looks so awesome... quite like leather
So this is one way to do it
And the PVA worked as well
but the shine is different. It's not smooth like the egg-- it's more 'sparkle' (it comes in dots)... but the shine is even
I used Liquitex gloss medium and the shine is similar to the PVA, but it is uneven. I'm guessing I just need to add more layers
