To ensure all pieces are included, compare the parts with the parts list in the manual. If any pieces are missing, contact LEGO customer service for replacements.
Sort pieces by color and type using small containers or trays. This makes it easier to find parts during assembly.
Ensure you are using the correct piece by double-checking the manual. Look for similar pieces that might fit better. Ensure all previous steps are correctly assembled.
Carefully peel off the sticker using a fingernail or a thin tool. Reapply it slowly, starting from one edge to avoid air bubbles.
Keep the model away from direct sunlight to prevent color fading. Dust it regularly with a soft brush or a can of compressed air.

Place the completed model on a stable, flat surface away from edges. Consider using display cases or shelves with raised edges to prevent falls.
