I always love to make personalized greetings card for family & friends and i have made this 3-D Christmas Tree Card from marthastewart:
They are easy to make and i love them esp. made them in RED and green papers hehee ..Try it and have fun (^.^*)
Card stock or blank store-bought cards
Star-shaped hole punch (optional)
1. Fold a piece of card stock in half or use a blank store-bought card. Cut art paper into rectangles of graduated lengths and widths (adding about 1/4 inch to widths and 1 to 2 inches to lengths).
2. Pleat each rectangle accordion-style, making same-size folds in each; score folds with a bone folder. Open card, and center rectangles in spine of card. Glue down end folds to form a pop-up tree that expands as you open card.
3. To make the "bucket" that holds the tree, fold another paper rectangle into four accordion folds. Glue end folds on either side of card's spine.
4. If you wish, use a star-shape hole punch to make a star for top of tree. Fold star at the center, and glue both sides to card.
