Adding tissue paper to a gift bag can help conceal the gift it holds. Depending on the size of the gift, small gifts can be wrapped in a piece of tissue paper before placing them in the bag while larger gifts may be placed directly into the bag. Next, lay your tissue paper out in front of you and pick up one piece by pinching it in the center and lifting it up. This creates a narrow bottom corner that can be placed down into your gift bag while the top corners are visible above the edge of the gift bag.
