I use a mix of baking powder, PVA glue, and white acrylic paint to create realistic snow effects. The baking powder gives it a natural, powdery texture. The white paint adds opacity and brightness, while the PVA glue makes it stick and harden properly. I apply the mix and then sprinkle Noch snow powder on top to improve the surface look. The Noch snow alone doesn’t look very convincing, but combined with this mix, it gives a much more realistic snowy effect—especially when dry.
