Six swan and four swan doily variations are given in the pattern.
This pattern uses UK crochet terminology.
This a vintage pattern so modern equivalents are a guess. You will need small amounts of orange and black thread in size 10 crochet cotton and a larger amount of size 10 cotton in white approx. 400 yards or so.
You will need a size 6(1.80mm) or 7(1.65mm) steel hook.
