A book of postcards to color by illustrator Chiaki Ida, a revised edition in Nihon Vogue's My Coloring Postcard Book series. The main character is a tiny girl who lives in a treehouse in the forest. Little birds deliver letters to her, and she goes for walks and picnics in a forest full of flowers, nuts and mushrooms.
It contains 40 postcards (20 designs, two of each), 2 large postcards, 12 mini cards (6 designs) and 10 color examples. The postcards are perforated so they are easy to take out. For this edition, the paper was upgraded to one chosen by the artist.
