From the Stitch Description: “Frost Flowers” is not the correct name for this lace, unless the author happens to be an unusually good guesser. But it is quite an old pattern, dating from at least the early nineteenth century, and therefore probably has its own quaint name by which it is, or used to be, known. In spite of its rather complicated appearance it is a simple lace, consisting essentially of only four rows, which are repeated three times and then alternated on the half-drop principle. On going once through the pattern these rows are quickly learned.
