It's been some time since I participated in any challenges, this one at CCCB sounds like fun to me.
I used Kraft Core Cardstock, the Tim Holtz Snowman, the trees are Unity Stamps. The frame is hand cut and I used my favorite embossing folder by Spellbinders.
The beautiful snowflake is out of my stash, but I still remember who gave it to me! It was Martina, she sent it for my birthday last year along with some other beauties!
