I have another white on white card to share today, made using items I've had for some years along with a couple of die cut trees which were gifted to me recently. I simply cut a square aperture in a piece of white card, backed it with an embossed falling snow design before adding the die cut 'snowflake' word and the trees. Glamour dust was added to the 3D elements for a bit of sparkle.
