A knit print is a fashion print made from cotton jersey -- just like a t-shirt.
A woven print is a fashion print made from high-quality quilter's cotton. This fabric does not stretch like the knits do.
These cotton prints are used for the outer print of fitted diapers and diaper covers/wraps. They are not waterproof fabrics. Below are the prints, woven and knit, you can choose from when building your own diaper or cover/wrap.
