From "Knitted Lace" by Sonja Essbensen and Anna Rasmussen.
The border looks rather squeezed in the picture in the book. I've modified row 53 so that there are four little repeats instead of five in the border.
The charting method used in the book is not particularly easy to follow and it gives no idea of the finished appearance or how the rows of stitches fit together. Stitch Maps is a great help in such cases.
Shown with a cast-on count of 20 stitches.
