The Highland Tweed fabric used in 1958 had an overall random check pattern; not uniform like a checkerboard, and colors above were combined with a white weave that made the cloth part of the seats appear lighter than the vinyl part. *This is most noticeable on the black fabric, hence the notation above.

The Softextured Vinyl used on the 1958 Thunderbirds had a horizontally-pleated design on the inserts, and the seats featured a silver tinsel welt that separated the bolster from the inserts.
