Gift boxes are a convenient way to wrap and give gifts to friends and family. You can purchase gift boxes at party supply stores although they tend to be rather plain. Boxes with patterns or pictures on them, however, can be expensive. Also, it's often difficult to find the right size box for what your gift. If you want to make your own gift boxes with lids, you can do so for little money using old greeting cards for smaller boxes or pieces of poster board for larger boxes.
Cut the two halves of a greeting card apart along the seam, using scissors. The front of the card will be referred to as piece one and the back of the card will be referred to as piece two.
Place piece one on your work surface, picture side down. Use a pencil to make an "X" from corner to corner on the backside of piece one, using a ruler. Draw an "X" on piece two in the same manner.
Fold in the long sides of piece one until they meet at the centre of the X you drew in the previous step. Fold in the short sides as well until they meet at the centre of the X. Use the side of a ruler to press the edges down and crease them. Unfold all four edges. Repeat this process with piece two; folding, creasing and unfolding the edges.
Place piece one on your work surface with the short side facing you. Cut a straight line up the creased fold on the left side of the card until you reach the creased line that runs horizontally. Cut the creased fold on the right side of the card in the same manner.
Turn piece one 180 degrees and repeat Step 4 on both the left and right creases, stopping when you reach the horizontal crease.
Place piece two on your work surface so the short side is facing you. Repeat Steps 4 and 5 with piece two.
Fold the long edges of piece two inward along the creased folds. Stop folding when the edges are at a 90-degree angle from the rest of the card. Do the same with the short sides of piece two, folding them until they are at a 90-degree angle. Tape the four sides at their 90-degree angles using invisible tape. This makes the box's bottom.
Repeat Step 7 with piece one, folding the short and long sides to a 90-degree angle and taping them in place. This creates the box top. Place the top on the bottom to complete your gift small box.
Increase the size of your box by using larger pieces of poster board. You can use any colour poster board and even paint or draw a picture on the box once complete.
