Painting mermaid Mishell (HELP)

I am painting little Mishell, she is a tiny mermaid baby for my sister for Christmas. I am having trouble figuring out what to paint her tail with. I want her tail to be shimmery and kinda wet looking…any suggestions?

Thanks!

I used air dry gloss varnish on every other scale and in the creases. I also bought a really love fine sand like glitter and used that at the bottom of the tail in the scale creases and folds of the tail. It turned out lovely. The picture does not really show it up.

Maybe Marlen will come along and tell you what she painted her mermaid tail with. You might message her here on the forum… her name is lamafer1101 or Marlen’s Sweet Dreams Nursery on Facebook.

Here is a thread about precisely what you are asking about.
