Bring hard-edged biker style to your stitching with this skull-and-engine design, built around a central skull framed by an engine block, supercharger intake and pistons. The crossed and upright pistons, flames, belt and pulleys give it the look of stripped-back workshop metal rather than a soft novelty motif. It suits riders, custom bike fans and anyone who wants a sharper mechanical look on women’s jackets, shirts or club gear.
With four thread colours in black, grey, white and light blue, the shading stays crisp and cool while the dense stitching gives the design a solid, filled-in presence. It works especially well on sturdy fabrics that can carry that heavier coverage, such as denim jackets, canvas vests, twill overshirts and the back of a hoodie. Use it where you want the artwork to read clearly from a distance and still reward a closer look with the engine details.
