One card is either a birthday or just friendship card, and the other is for Christmas. The first one is the one that meets the two challenges.
I tried to be a bit edgy but think I am too old to be edgy! That is a piece of plastic waste and the card and DP are scraps, attached to a piece of SU So Safron card. All inks used except the stems on the trees are SU, and the stems are Momento Tuxedo Black. The bow is Papermania.
The second uses the same stamp set with the tinsel embossed in gold, and the sentiment and stars just stamped in gold. The whole is mounted on gold mirror card, and then a piece of Kaiser Christmas Collection paper. The whole is then on a blank of aqua Bazzil card.
