Kancheepuram sarees, also known as Kanjivaram sarees, are famous for their rich silk, intricate weaving, and heavy use of zari (metallic thread, traditionally gold or silver).
The types are often distinguished by their weaving technique and design:
Based on Weaving Technique/Design:

• Classic Kanjivaram (or Traditional Kanjivaram): The quintessential saree, known for its heavy weight, rich drape, wide and contrasting borders, and traditional motifs often inspired by temples or mythology.
• Korvai Kanjivaram: A unique style where the border and the body of the saree are woven separately and then meticulously interlocked, often featuring contrasting colors for a striking visual effect. This is a highly valued and time-consuming technique.
• Thread Brocade Kanjivaram: Characterized by raised patterns and intricate motifs woven using extra weft silk threads (instead of or in addition to metallic zari), giving a beautiful relief effect.
• Zari Brocade Kanjivaram: Features extensive and intricate designs woven into the body or border using metallic zari (gold/silver/half-fine), creating a shimmering, opulent look, popular for weddings.
• Pattupettu Kanjivaram: Known for simpler, often geometric designs like checks or stripes, and is generally lighter in weight than the classic varieties.
• Butta or Butti Kanjivaram: Features small, scattered motifs (‘buttas’ or ‘buttis’) woven onto the body of the saree, which can be traditional shapes like mango, peacock, or lotus.
  Other Variations:
• Temple Border Kanjivaram: Specifically features a border design with triangular or zigzag patterns, reminiscent of temple architecture.
• Plain Kanjivaram with Contrast Border/Pallu: Focuses on a simple, plain silk body with the elegance provided by the contrast-colored border and pallu (end piece).
• Dual-Tone Kanjivaram: Achieved by using two different colored threads for the warp and weft, creating a shimmering, iridescent color effect that changes with the light.
• Contemporary Kanjivaram: Incorporates modern colors, patterns, and design elements while retaining the core Kanchipuram weaving tradition.
