Flat seam construction for automotive upholstery

A flat seam construction formed on a portion of one or more stitchable automotive upholstery materials said seam construction having a number of sequentially formed stitches, each stitch comprising:

• i. two outer threads, formed into first and second outer thread loops, and at least one inner thread, formed into at least one inner thread loop;
• ii. said first and second outer thread loops spaced across a width of said seam construction, and said at least one inner thread loop positioned between said first and second outer thread loops;
• iii. each of said inner and outer thread loops transversely penetrating said one or more stitchable materials;
• each of said inner and outer thread loops having a bight portion engaging a bottom surface of said one or more stitchable materials;
• iv. at least one looper thread formed on, and coplanar with said bottom surface, and arranged such that, said at least one looper thread passes between said bottom surface and at least one of said bight portions;
• v. at least one decorative thread visible on a top surface of said portion of one or more stitchable materials and extends across said width;
• wherein said at least one decorative thread loops around at least said first outer thread loop at a penetration point thereof;
• and
• wherein said at least one looper thread comprises four looper threads, each passing through said bight portion of a respective one of said inner and outer thread loops.
