The Birthday Cake Stamp is on page 16.
I found the original idea here... Mary Fish always can bring a great idea to be CASE'd.
Supplies used to make this card were:
Pacific Point Cardstock, Real Red Cardstock, Whisper White Cardstock, Fresh Prints DSP, Birthday Cake Stamp, A Dozen Thoughts Stamp Set, 1" Square Ounch, Itty Bitty Punch Pack, Brights Candy Dots and Pacific Point Ribbon.
I love how it is Red, White & Blue!
Have a great day!
