The doilies in this pattern are quite common, and the basic patterns are the same in books from all over Europe. I’ve included some small images from a Russian book I found online. I think because they are so widespread, these doily designs are a kind of universal European folk art.

The Catalonian and German doilies as well as many of the doilies in my Russian book, are finished off with a crochet chain bind off that added an edging of small picots to the design and made blocking the curved shapes quite easy.
