My name is Sarah Koehler
and I am the owner of Sostre Self.
I am a mom, wife,
daughter, friend, and sister.
I live in Baileys Harbor, WI
on the "quiet side" of Door County.
I love delicious food & a great brainstorm.
Hospitality is not only a true love of mine;
it’s how I’m wired.
In order to be all the things,I have to prioritize me.
I am SO excited to finally share my products
I have been making for years!
Thank you for being a part of something so special.

Take care of you for me.

(søstre : so-struh) SØSTRE: Norwegian for sister


By surrounding myself with a collective of inspirational women

I found my own SELF​

and my passion for self-care evolved into products, ideas and art. 

Søstre Self started a long time ago without me even realizing it. It's my journey in self care through food, exercise, natural products, and my art. It started over cups of coffee and tea. It started over glasses and glasses of wine. In restaurants and in kitchens. In pajamas and bridesmaid dresses. I'm lucky to have an amazing circle of strong, independent, beautiful women who I call my sisters. Who brainstorm, support, and love each other. My health journey started at age 13, because of a kidney disease diagnosis. My exercise journey started only two years ago in hopes for more energy to keep up with my son. My need for natural skin care started in 2015 during my pregnancy, because of my sensitive skin and continued because of my son's. And my art started when I was a child when my mom and I would pause animated movies and draw images. And now, I finally get to share it ALL with you!

Søstre Self is my way of sharing how I got here and hopefully I can help you in finding yours.

Brainstorming, supporting, guiding, and sharing; together.

Søstre Self is truly a sisterhood.

Inspiration for my artwork comes from my surroundings in Door County and wherever I travel. I explore with scribbles and exaggerate with color. To get there I use watercolor, soft chalk pastel, acrylic, or mixed medium. I draw on impulse and love to be extra playful with line. It gives each piece a personality of its own. Keeping it loose and fun helps me stay connected to my whimsical side and simply surrender to the innocence of true play. I create from the heart and my work is intended for those who want to smile.
