I was thinking of general embroidery blanks rather than specifically hankies.
Did you notice that ATG has 2 different hankie designs for ladies? I particularly liked this pineapple design that my mother crocheted many times. The simple lace design is excellent as well.
Wedding hankies are very special, embroidery adds just the right touch. I hope you have an opportunity to photograph them for us to see.
Best wishes to the bride and groom and you and yours, Pat
