This issue's concept is creating a spring-themed postcard for friends, with pink as the main color. I used watercolor cardstock as the base (perfect for postcards or photo displays), layered with beige-pink patterned paper as the background. 

To avoid an overwhelming pink scheme, I added green plant PET stickers to bring vitality. Combined various pink/beige papers with red line flower PET stickers for depth. Then added the star element - a pink butterfly fairy PET sticker (matches the card texture). 

For 3D effects, apply butterfly PET stickers by only adhering the body center, leaving wings free. Finally added romantic text and wax seal stickers to create a letter-like feel. Voilà - a pink-themed postcard complete!
