Let’s start with wax resist
Wax resist — aka batik — is a very old way to make fabrics. It began in Indonesia, got mechanised in Europe and the patterns became wildly popular in West Africa.
Right, tell me more
Etched rollers print designs in wax on cotton cloth. The waxed parts then ‘“resist” the dye, leaving a pattern, with more detail printed on top.
Personally, I’m more interested in the result
Well a lovely artisan effect usually has a bit of “crackle” where dye seeps through the wax.
