When I first saw this pattern it was made as doily( table centerpiece).
Almost year later found it in Muhv's blog . She got tutorial from Estonian lace making course where she learned to knit world famous "Haapsalu sall" (click on pics to see bigger, also there is few words in English in bottom of page) .
The "nupp"(knit 5 from 1stitch,purl 5tog at next WS row) is also originally from Estonia as well.( I hope you knew that! ;))
This beautiful lace shawl is knitted from Estonian lace pattern with cobweb weight mohair yarn and 3.4mm knitting needles.
Already designed and started next one:
Lilly's Leaf Shawl pattern.
