Cotton Lycra is the king of jersey!! It is what you will recognise from the high street as t-shirts, dresses, leggings, baby clothing. But what you will find is that the cotton lycra you buy is much better quality, and longer lasting than fabric on ready to wear clothes.
Brushed poly behaves in a similar way to cotton jersey, but its brushed texture is soft as a peach. It's super stretchy and super soft.
