Tracing paper, a translucent paper used for tracing and transferring designs, can be known by several synonyms. Vellum tracing paper, or simply vellum, is a smoother and more durable tracing paper commonly used for drafting, sketching, and technical drawing. Parchment paper is another type of tracing paper that has a semi-opaque quality and is often used for tracing and transferring designs in art and crafts. Drafting film, or mylar, is a more durable and stable film-like tracing material that provides better accuracy and precision in technical drawing and architectural designs. Finally, onionskin paper, a thin and lightweight tracing paper, is commonly used for tracing and copying documents and manuscripts.
