The pattern came from Purl Bee, and was super cheap--like, less than $10 to make thirty-two ornaments. (I bought my glittery felt from a local craft store.) It was, admittedly, a bit labor intensive to make so many--overall I think it took me about five or six hours--but if you break it up over a few days it's not too bad. (You could always make less too.)
And I love the thought of my little glittered snowflakes blowing out all over the world!
