My quick solution was to go with a neutral Soft Vanilla background for the card and one color of ink: Chocolate chip. I used my scallop square and 3/4" punches to give this card some added interest. Notice that I mounted the punched out circle element from the b is for birthday stamp on the brown scalloped cardstock. By mounting the simple, 1 color stamped element onto a vibrant color that shows through the center of the b, it gives the card a focal element against the neutral tones used throughout. I used my glue glider pro with Perma Tac adhesive on the card and used some Crop n' Glue Ribbon Adhesive to mount the knotted ribbon. Duplicate this card idea in 5 minutes or less using the Party Hearty stamp set from Stampin' Up!® along with your color choices.
Some other fun color combinations to try:
White, Black, Grey + Vibrant color
Or try some monochromatic colors: Pirouette Pink, Pretty in Pink, Riding Hood Red or Bravo Burgandy Or mix in a patterned paper in place of the wheeled pattern or scallop punched CS.
Remember that when you get discouraged, head to your stash pile of pre-stamped items, paper scraps and extra embellishments to kick start the process. You will feel so satisfied when you get to "recycle" those into a fantastic card or project. Happy Creating!
