Perlé cotton is a form of mercerised cotton thread that became available from the 1920's onwards. Perlé is a non-divisible thread, usually Z-plied and s-spun. It is regarded as a strong thread with a lustre. Perlé (also known as pearl or French perlé) was initially made by DMC, but was later copied by other companies.
