I just posted a great vintage pattern which will challenge the lace knitters out there: the Peacock Doily.
This lovely knitted square doily from 1954 will make any proud possesso the talk of the town. The original was made in white and measures about 17 1/2 inches square. You will need one large ball of number 30 crochet cotton and for greatest ease of working, you should use 5 double pointed steel knitting needles size 13 or 14 (old US). / 15 or 14 (UK) / 1.75 or 2 (mm) / 00 or 0 (US).
