Question about selvage
 

What does the number mean on the selvage when they are in parenthesis:
Example---I bought the same fabric at two different times, and one says (S16) Camelot Fabrics,
and one says (S17) Camelot Fabrics.
Does that mean a different time it was run?
Thanks.

Interesting. i've not noticed that yet myself.

I haven't noticed it either. Could it be a dye lot?

I would maybe guess that it is dye lot or a second bolt of same fabric. Actually, I have never noticed #'s in parenthesis.
