What's the difference between tie-dyeing, batik and blue calico?

Tie-dyeing, batik and blue calico are all traditional handicraft varieties of textile dyeing.

Tie-dyeing, also known as twist dyeing or twist dyeing, is to tie, tie, sew and tie the fabric with rope and thread, and then put it into the dye solution for boiling dyeing.

Batik is to use the water-repellent property of wax to draw a decorative pattern on the fabric first, and then immerse it in dye solution.

Blue calico, also known as grey dyeing and indigo calico, is repeatedly dipped and dyed by the process of hollowing out, carving and scratching to prevent dyeing and form the beauty of simple blue and white patterns.
