One of the best places I have found for bib and burp cloth blanks
is at
EMBROIDER THIS.
But I also get my bib blanks from where my SIL works as she can
get them for me at her cost (employee discount). If your able to
buy wholesale than
Imprints Wholesale might be an option for you.
PLUS Imprints has 14 colors (white terry bib with color binding) to
choose from.
