Looking at the pics, i THINK that... the pink speckled and the floral on white that are pictured together are cotton.
That the fabric scrap - pink floral, pictured with them is a cotton blend.
That the white on white is cotton,
That the pink on tan is either cotton or a blend... i think cotton.
The pink gingham is a blend, i know...
The pretty patchwork floral is a quilt cotton and the lilac is a blend. Although i may be wrong. )0:
The one thing i CAN say without unpacking this is that they're NOT all cotton, but a few are. No poly's as far as i can tell. A couple of cotton blends though.
