I've been trying to post a reply since this thread was started .... everytime I get booted >
My personal preference is for snow to be smooth and slick (maybe that's because because my carvings are rough and fuzzy :-[ ??). The only place I really use/need snow is on a base and when I first started I slowly and carefully carved each tiny drift, drip and swirl. Took me longer to do the base than the carving!!
Now I buy something called 'Texturing Paste' at any craft shop or even WalMart (it's just a thick, white acrylic gunk), stir it as much as I can and glob it on the base and let it hang over the edges. It smooths out under its own weight (but it will crack if applied too thickly). After it's dried a day or two I paint it with my regular acrylic paint and I'm ready to go.
Rick, I've bought the Snow-Tex stuff too but it has glitter in it and IMHO glitter is a bit too .... hmmmmm..... can't think of word. I just don't want glitter in my snow but have no objection if others do.
