One of my favourite ways is using the chunky white Frantage embossing powder - sprinkling it on and then heating from underneath so that you don't blow it off the cardstock.
I started by stamping the tree in Versamark and heat embossing in white. Then I created a mask for the snowy ground and sponged around the tree with three shades of Distress inks. I removed the mask from the horizon and added it lower down so that I could lightly sponge a bit of a snowdrift.
Then used the chunky white frantage all over the panel.
I finished off by added die cut doves and a die cut sentiment, and popped the panel up on fun foam.
It's for my best friend who loves blue and white, and only likes Christmas cards that have a theme of "peace".
