Hey thanks, Mike!
Haha, yeah it ended up being a lot of snow. To bond it, used WS Flex Paste on the lower left corner of the layout (outside the tracks), all of the hillside around the raised tracks, the back left cliff, back right hill, and center hill where the Christmas tree will go. In the flat areas, I used a water/pva/alcohol mix, and literally filled the area with a thin layer. The microspheres didn't immediately pull into the glue, so I had snowy puddles jiggle if I bumped the table. Lol.
Haha, glad my shenanigans could provide a laugh!
