A traditional acorn design with deep, pronounced vertical ridges in rich brown tones with darker burnt sienna accents. The illustration uses detailed cross-hatched shading technique and vintage line work style. A textured cap with natural crosshatch patterns sits prominently on top, while ornate oak leaf tendrils with small detailed leaves create decorative flourishes around the sides. The acorn has a full, oval silhouette with deeply defined vertical segments and classic proportions. The cross-hatching creates rich depth and dimension throughout the design, emphasizing the classic autumn harvest aesthetic with the same artistic approach as a traditional pumpkin illustration. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
