For the souvenir stickers, we chose a screenshot of the video as the main motif and overlaid it with some colors and textures. We also chose some words that describe the qualities of the life stage. Two versions of the sticker were created and we finally chose one of them. For the souvenir card design, we set up an area for each life stage to put stickers on. Once visitors have chosen the stickers for each stage, they can stick them in the corresponding area.
