I'm sure there's no absolute right answer, but what method have people been happiest with when creating snow effects on bases? Is it worth it to buy a "modeling snow" product or is baking soda just as effective (and probably cheaper)? And if you do go with a manufactured kind, do you have a preference? I've seen a lot of stuff out there promoting Woodland Scenics stuff over GW and GF9, but I'm sure a lot of that's completely subjective. Also, as good as some of the videos and photos posted are, it's obviously difficult to get an accurate assessment of texture.

Any ideas would be greatly appreciated!
