Smoke works particularly well with gray, silver, charcoal, black, white, and denim blue. Use it over similar gray fabrics for a coordinated finish, or place it against lighter fabrics when you want the stitching to remain visible without creating a bold contrast.

For a balanced neutral palette, consider pairing Smoke with Superior Threads So Fine! #50 white for lighter areas and Superior Threads So Fine! #50 black for darker fabrics. These complementary neutrals give you flexibility when working across multiple fabric values in a single quilt or sewing project. Check the actual shades against your materials to determine the best match.
