Create a new file 5″ x 7” at 300pix/inch in RGB mode. Color the background layer with a blue linear gradient.
Copy it (CTRL+J on PC or Cmd+J on Mac) as much as you want – resize it and plant it all over your Christmas card.
You can resize it freely because it’s vector format and it will not loose a bit on quality.
Color them in different tones of white and blue to create an illusion of depth, 3rd dimension.
Create a new layer (CTRL+Shift+N on PC or Cmd+Shift+N on Mac), use snowflake brush from brush set “Grunge Snowflakes Brush” – spread snowflakes in different sizes all over the background.
Color the layer with the snowflakes with “Gradient Overlay” from white to approx 45% of cyan.
Now you can write “Merry Christmas” or “Happy New Year” and Christmas card is finished!
… or if you don’t feel like going through all this but would like to use this file for your needs – download the original file for less than $1 🙂
