Here is another fun & bright card from my upcoming Birthday Bash Stamp-a-Stack. The main image stamp features numbers from 0 to 9, plus "st", "nd", "rd", and "th". You can simply highlight the number for any birthday, as I have done here for a 5th birthday. I stamped the image with Black Staz-on ink, then colored the numbers with Bashful Blue and Real Red markers.
This would be a great card to have on hand for upcoming birthdays. I plan to keep a couple for those last-minute parties that my children always get invited to. :0)
