The two first cards are both using the festive flurry stamp set. The first card was stamped with silver Encore ink and then embossed with silver embossing powder. The coloured card stock is Coastal Cabana.
The second card uses Midnight Muse and Soft Sky
Note, you could easily use also the Snowflake Soirée stamp set to get the same results (although you don't have the matching framelit to cut the snow flake out for the first card)
