Dear Cindy,

Real barkcloth is just what the name says; it's a cloth made from
pounded bark. The bark has resin and fibers in it to hold it together.
However, there are home dec fabrics that resemble bark and are called
bark cloth, but are made from the usual fabrics. If it's all cotton,
the "bark" effect will be removed with washing. It's also scratchy,
and wouldn't be suitable for Hawaiian shirts.
