Tea Cosy (bottom right) 8" height with a tension of 7.5 sts, 9.5 rows to 2" over the square pattern.
Coffee Cosy (bottom left) No size given only to fit an average percolator. Tension is 3 sts, 4.5 rows to 1" square.
Tea Cosy (top photo) 20" all round lower edge and with a tension of 4 patterns equals 4.5" wide and 3.25" depth.
I can't find any information on this vintage yarn, so you should definitely do a tension piece with a substitute yarn.
The pattern has some creasing but overall good vintage condition.
Circa 1940s/50s
