In cardmaking, a card blank is a pre-cut and folded cardstock that serves as the foundation for creating a handmade card. The card blank is typically made of high-quality paper or cardstock and comes in a variety of colors, sizes, and shapes to suit different design preferences. Card blanks can be decorated with various embellishments, such as stickers, stamps, ribbons, and patterned paper, to create unique and personalized cards for different occasions like birthdays, weddings, and Christmas.
