Point Lace pattern from the book Le Dentelle Renaissance (Renaissance lace aka Tape Lace) by Thérèse de Dillmont. In the public domain. This book had the patterns printed on linen cloth and attached in the book.
About Romanian crochet and the techniques to make it. Please don't post American style of macramé as the Romanian is the same as the point lace and has nothing to do with the American version just a different term used for the same thing.
