minä perhonen: skyful (Yellow) Weeks Cover Only - Techo Lineup

minä perhonenskyful (Yellow)Weeks Cover Only

2026 New

minä perhonen creates timeless, all-original garment textiles that are specially dyed, embroidered, and woven to recreate hand-drawn designs.

This item is a reimagining of the popular 2014 Hobonichi Techo cover skyful. This time, the color scheme was specifically created for the Hobonichi Techo cover, which depicts a sky full of stars made from colorful, brightly embroidered dots.

The base material is a soft cotton fabric. Two different types of thread were used for the embroidery, creating both a tactile, bumpy texture and a difference in lustre between the two.

The cover interior is in a vivid yellow. The pen hook is designed to hold a pen by its clip.

The zipper pull is made out of a natural leather, and the butterfly-shaped fastening adds a cute charm.

A comforting techo cover to make you feel at peace, as you take your Hobonichi Techo with you on your daily adventures.

Also available is a small tote bag made with the same textile.

About minä perhonen

minä perhonen is a brand created by designer Akira Minagawa.

First founded in 1995 under the name minä, and renamed “minä perhonen” in 2003. In Finnish, “minä” means “I,” and “perhonen” means “butterfly,” expressing Minagawa’s hopes to create designs as light-hearted and beautiful as a butterfly’s flapping wings.
