Then I found a website on Lacemaking in Poland. You can see more beautiful work here.
Other interesting sites: People from Poland and crochet
1. Dorota's Etsy Store - nice crochet items!
2 Frezje's Etsy Shop - Cute doll dresses! (scroll down to see crochet)
3. Eva Crochet - Pretty filet crochet
Kroowka - More Polish lace on Etsy
5. Vintage Victorian Crochet - I found this quote on "crochet was quickly picked up from the French by Polish thread workers and many of the lace patterns were designed, and are still made, in Poland."
