Vintage American Thread Co. Star Crochet Cotton

The original vintage box might have seen better days, but the crochet thread looks brand new! Definitely not new, but clearly never used, and looks like full spools.  12 spools — 8 spools variegated light pink & white, 1 spool varigated dark pink & white, 2 spools dark pink, 1 spool medium pink.

I haven’t tried embroidering with it, but it looks similar to a size 12 embroidery thread.  Maybe another use for it?
