Ooh I like that idea! I am doing "Dashing thru the Snow" theme in our sunroom this year. I have a rug and sign that says that so far, lol. Snowflakes hanging would be sooo awesome! Thanks!
ETA:also, and I don't really know if this works for you, but they have ornaments that look just like snowballs -I think I got mine at a craft store??? And they look really cute sitting around or in a bowl or something - not flakes I know, but I thought maybe they could go along with it??
