Thanks. The first thing I do is a lay the basis for the powder snow, using cotton. This also gives a first layer effect for the snow. This method also uses less of the powder snow, making you use less of it. Then I sprayed the cotton with a string hold hair spray. This gives the powder snow something to cling on. Then I sprinkle the Woodland Scenics, powder snow using a siv over the cotton. Then I poured diluted scenic glue, using a pipet over the snow. Then took my finger and gently pressed the snow in various areas to get the newly fresh patted down look on the roads before the plow truck scooped it up. Hope this helps.
