inner layer

That was my look, at least my inner layer, for a long hot week (during which there was a blizzard).

A thin inner layer of green birch bark, or a piece of paper, if one has it, will do for a wrapper.

Here she filled a jar with bits of the inner layer, then, pouring water over it, let it stand for a week.

Usually the outside is white and the inner layer brown or coffee-colored.

The outer layer of their bodies is harder than the inner layer.

The bark is thicker than that of the true root, and the inner layer is usually dark brown.
