Materials and tools needed to make a three-dimensional puppy with cardboard: square colored handmade paper, scissors, glue, adhesive tape, marker or colored pencil.

Step 1: Take a square piece of handmade paper, fold it in half along the horizontal center line, and then fold it in half to make it a quarter size.

Step 2: Fold in half.

Step 3: Draw a banana's tail shape on the bisector on the left side of the center line and cut this line with scissors.

Step 4: Open the paper completely after cutting.

Step 5: Fold the left part of the vertical midline down to the right except the tail, and fix the overlapped two parts with transparent tape.

Step 6: Fold the horizontal centerline up and down to make the tail stand out. Then draw a puppy outline.

Step 7: Cut off the part outside the contour line.

Step 8: Fold the tail root line to one side to form a fold line, and then fold it between two layers of paper along this fold line to make the tail tilt.

Step 9: Paste your eyes and ears, and draw your mouth and nose. These can all be drawn with strokes. If children like painting, then everyone's puppy can draw differently, which is very interesting.
