Watermelon & Smoothie Summer Mini Postcards Set — 10×10 cm | Zolota Ptakha

This set leans on watermelon pink — slices on yellow grid, a smoothie cup with a striped straw, an “It’s Summer Time!” with painterly lines, and a final “hello Summer” framed by another wedge of melon. The 10×10 cm square on 350 g/m² stock keeps the colour block strong inside a journal spread, a fridge magnet wall or a postcrossing envelope.
