"用拼花图案装饰" can be translated into English as "decorate with mosaic patterns" or "adorn with patchwork designs", depending on the specific context and the type of pattern being referred to.
"Decorate with mosaic patterns" is often used when referring to intricate, tile-based designs, such as those found in flooring, walls, or artworks.
"Adorn with patchwork designs" might be more appropriate when describing a design composed of smaller, often colorful, pieces of fabric or material sewn together to form a larger pattern, though this is less common in the context of hard surfaces like floors or walls.
For general purposes, especially when referring to architectural or interior design elements, "decorate with mosaic patterns" is a more commonly used and accurate translation.
