I am a real summer person, but I do think that snow in moderation (as in not 4+ feet snow for 6 months) is beautiful. I LOVE snowflakes! They are so beautiful! (See my TUTORIAL on window glue gun snowflakes to see just how much I love them)
I couldn't resist doing a graphics post just on the topic of snow.
