🌄 Knobstone Resale 🌄

Knobstone Resale is part of our creative work under Altared Horizons — same family, same owners. We’ve realigned with our regional roots to reflect the values our family is built on.

We’re a small, three-generation family business: myself (Phillip), my daughters Neko and Aces, and our matriarch, Nana. Together we handpick and prepare every item you see here.

Nana is the heart of our home, with her love of sewing, reading, and classic movies. Neko is our artist and cat-lover, always sketching and dreaming of Japan. Aces brings her creativity, distinctive style, and love of stories.

I’m Phillip — I design shirts, play music, and hunt down retro treasures. I’m transitioning from traditional work into a life of creative stewardship, blending resale, storytelling, and heritage work. What I once did for a paycheck, I now do with purpose: reclaiming forgotten things, preserving local history, and shaping a living archive of our region’s culture and craft.

Every purchase helps support our family’s future and keeps these finds in circulation for the next generation.

Thank you for supporting Altared Horizons!
