Oh wow, a living quilt! I’d start with a smart‑thread base that can change color and temperature—think conductive yarn woven into a fine, neutral grid. Then layer your favorite fabrics on top, but keep each layer thin so the tech stays flexible. I’d use a simple “tension‑balance” stitch to keep the layers even; that way the smart core stays centered and you avoid a wild tangle of threads. Finish it with a snug, breathable backing that lets heat flow, and you’ve got a patchwork that’s both comfy and responsive—no nightmare of mismatched threads, just a cozy, smart hug.
