I wonder if your "baby wraps" are what we call "diapers". I think the Brits call them "nappies". That is a very loosely woven cotton fabric.
Anyway....Muslin does come in different weights and is solid cream or tan in color.
I also have some bleached muslin that is a very nice weight cotton for quiltmaking and I have also used it for printed labels.
In fact, I
think it may be the base fabric that Ricky and Justin use for their wonderful hand dyed pieces!
And....when we call a fabric "calico" it usually refers to a printed fabric....often with a small print like the 30's reproduction fabrics.
I found this labeled typical American calico on Pinterest:
