post-it-notes for masking.  You'll use these to create the grid lines and to mask off a section to stamp within a grid section
sponge
ink, card stock, stamps

For this card, I used Night of Navy to create the diagonal line, and for the snowflakes, and greeting.  I used Highland Heather, Purple Posy, Pear Pizzazz, Rococo Rose, and metallic silver inks for the grid sections.  

 

1.  Lay 2 post-it-notes at an angle on 5" x 3 3/4" Whisper White card front.  With a sponge, add Night of Navy ink along the edges of the post-it-notes.  Often with sponges, you dab, dab, dab on the ink.  With this technique, swipe the color along the edge of the post-it-note.  I start swiping on the post-it-note, moving the sponge just beyond the edge.
2.  Don't remove the post-it-notes yet.  This can be a messy technique with ink getting on your fingers and on parts of the card front you don't want it on.  Keep the post-it-notes in place to protect the bottom part of the card front.
3. Lay post-it-notes on the top part of the card front, creating a section of open space.  Sponge a color within that section.  Move the post-it-notes to create another section of open space.  Use the post-it notes to mask off areas already sponged with color. Sponge a color within that section.  Continue moving the post-it-notes, creating sponged sections until complete.
4. Stamp the snowflakes from Frosted Foliage using Night of Navy ink over all of the sections.
5. Remove the lower post-it-notes.  Stamp greeting.  I used the Stamparatus.  
6. Attach to Silver Foil mat.  Attach to Night of Navy card base.  Attach Metallic Pearls to complete.
