It is easy to make this fun card by using several brightly colored pigment inks. Using a sponge dauber, dab the applicator on the pad using the color you want and streak it along the page. Do this several times using different colors, cleaning the dauber between each color and blending the colors together as you go. Then, sprinkle on hologram embossing powder and heat with your heat gun to add a bit of shimmer.
To embellish the card, stamp and cut out Sledding, shape the paper a bit in the palm of your hand so it has a bit of dimension (see this post for more about the 3D paper craft technique), and attach to the card using foam dots so it is raised off the surface a bit. Finish with the greeting of your choice, written in a fun, decorative script:
