minä perhonenpiece, (Weeks Mix)Weeks Cover Only

  • 2026 New
  • HOBONICHI STORE ONLY

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



The popular piece, series consists of covers made from scraps of leftover fabric produced during the construction of clothes. These pieces are then lovingly hand sewn into a patchwork fabric. By combining textiles that use a large variety of materials and construction techniques, an entirely new fabric is born.



The Weeks Mix uses 9 different types of fabrics with flower motifs, including “flower fog,” “felice,” and “flower leap” from the 2024-2025 Autumn / Winter season. These textiles have movement, almost like grass and flowers that are dancing in the wind. Additionally, the “rosy,” “tarte,” and “tambourine” fabrics add a puffy, tactile texture to the final product through their embroidery.









The cover interior is made from cow leather in a smoky pale blue. It’s accented on the top left with a butterfly embroidery.









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.



As each piece is cut differently from the original fabric and the stitching is done by hand on a sewing machine, each cover is truly a precious one of a kind.



*Please note that while the piece, series was previously sold through lottery sales, since the 2025 edition, it is sold through normal sales. Additionally, for the 2026 editions, there will be no Spring version piece, available for sale.

Fabrics used for the piece, (Weeks Mix)


1.tarte (2007-08 Autumn / Winter)

Ovals that surround colorful stitching are lined up neatly on this fabric. A design that was inspired by rows of vibrant and shimmering tarts in a display case.

2.yula (2021-22 Autumn / Winter)

Flowers are gently swaying in a warm breeze as they bloom towards each other on this textile.

3. jellybeans (2002 Spring / Summer)

Soft-colored droplets, almost like rain drops made of light have fallen onto the cloth, are layered in this pattern. Each droplet is designed in soft, luminous watercolor colors.

4. tambourine (2000-01 Autumn / Winter)

Circles are formed through a lineup of tiny embroidered dots with their own unique expressions.

5. flower fog (2024-25 Autumn / Winter)

A design inspired by the fog swaying in the wind, envisioned as tiny flowers. As soon as they appear, they disappear once more—this fleeting scenery is expressed through a jacquard fabric.

6. kaleidoscope (2011-12 Autumn / Winter)

The world of geometric patterns born every time you spin a kaleidoscope. The material used is a velvet jacquard, which has a sense of depth.

7. felice (2024-25 Autumn / Winter)

Birds and butterflies gently approach the flowers on this fabric. A textile that conveys the message that we exist to share joy with one another.

8. rosy (2018-19 Autumn / Winter)

A rose motif is embroidered in several layers, making it look like an oil painting with a simple and gentle expression.

9. flower leap (2024-25 Autumn / Winter)

Small flowers ride the wind to sway around in this design. The embroidered dots and flowers are structured in a rhythmic pattern.

*The year in brackets indicates when the fabric was first released.

Please Read Before You Buy

We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.

Inquiries cannot be handled by minä perhonen stores

This cover is produced and sold by Hobonichi Co., Ltd. under the design direction of minä perhonen. Inquiries about these covers cannot be answered at minä perhonen shop locations, so please contact the Hobonichi Store with any questions or concerns.

Patchwork patterns vary by cover

While the same textiles are generally used for all patchwork covers, the specific sections of fabric vary from piece to piece. In some cases, fabrics with slightly different colors or patterns may also be included. As a result, each cover has its own unique design.

Fraying may be visible on lace bookmarks

The bookmark features original lace ribbon from minä perhonen, which may show some fraying. If you notice fraying, please do not pull the threads— instead, gently tuck them back into the weave of the ribbon for continued use.

Threads may protrude from embroidered area

Please note that embroidered areas may contain threads that protrude from the design.

Leather may contain preexisting wrinkles and marks

In order to allow customers the enjoyment of all-natural leather, the leather is processed in a way that retains its original feel. This may leave imperfections visible on the surface of the cover, such as wrinkles, scratches, stains, or vein marks.
Depending on the conditions in which the cover is used, natural oils of the leather may emerge and appear as stains. We ask for your understanding for these naturally-occurring characteristics of genuine leather.

Using the pen hook

This pen holder works by holding the clip of a pen. Certain pen sizes or shapes may make it difficult to close the cover zipper.

Color transfer may occur due to friction, pressure, or moisture

Color may transfer to other items through friction or prolonged contact. This risk increases when the cover is exposed to water or sweat, so please take extra care when carrying it near clothing or other belongings.
