I’ve seen many complicated tutorials around the internet on how to give your text that “snow covered” look for holiday projects, christmas cards, whatever. It’s not really as difficult as it may seem to make your text look “snowy”, it’s as simple as applying one layer style and changing the settings.
Start out by creating a new layer, giving it a background color other than white and using the type tool, type the text you want to have covered in snow. Then double click on the type layer to the left and choose your type color (I used #587295) and apply any other layer styles you might want.
