I've written up the shawl pattern, and added it to my Ravelry store...
Width (across the longest side): 68 inches
Length (from center to point): 34 inches
About 500 yards lace weight yarn. Sample is knit from 2 skeins of Ariel from the Natural Dye Studio (100% silk; 250 yds per 35 g/1.23 oz. skein). Ariel has been discontinued, but most lace weight yarns would substitute well.
US size 4/3.5 mm 24-inch circular needle
105 small beads (if desired)
crochet hook (small enough to fit through hole in beads, if desired)
Not crucial for lace; select a needle which produces fabric you like, and creates good contrast between YOs and stitches.
Price: $4.00, from Ravelry, or my Etsy shop.
