I don't think either has been used.

The blue flannel one still has its original cardboard tag.

The pink is not flannel but not sure what the fabric content is.

There are no tags to indicate size.

The blue flannel with bunny rabbits measures approx 16" inches in length and laying flat 10" inches from armpit to armpit.

The pink floral is 18" inches in length and 12" inches laying flat from armpit to armpit.
