this one and this one. Here's what I came up with.
The greeting is printed on the white layer which is adhered to the card front. I then punched black snowflakes with a punch from Emagination Crafts Corp. For the center one, I layered a medium white confetti snowflake and a small confetti one in an iridescent color onto the black all held in place with a tiny black brad. This was repeated on each side above the greeting.
