There are many options for gamers when it comes to simulating snow effects on miniature bases; personally, I like taking the homemade route. With a few minutes and a few inexpensive supplies, you can create effects such as these...
(click on any images below for larger pictures)
~White Glue(such as Elmer's)
~White Paint(preferably inexpensive craft paint)
~Container for Mixing(old blister or dixie cup, etc.)
~stick(or paint brush) for mixing
~old paint brush
Before going on, I must warn: do not leave out the paint! It might seem excessive as the baking soda and glue are white(the color of snow to the eye!), and, your mix would even be white without the paint. However, after a couple of weeks the snow will yellow as it oxidizes...and of course yellow snow is something different entirely(maybe appropriate for Khadoran War Dog basing). Including the paint prevent this.
|This small batch would easily accommodate over 30 bases...a little||goes a long way!|
(I went for a shallow, dusting of snow)
Here's the entire Kossite unit done with this effect...
Also, this same snow mix is a great way to accessorize terrain pieces for a winter themed board as you can see on some pieces that I've done below...
