They are made from scraps, so have a rummage through your stash and if you've got 50g of 4-ply or fingering, you'll have enough to make these. And they are on 2 needles too so no fiddly dpns to deal with although you could probably convert it to in the round if you wanted.
Clothing started to be restricted in 1941 and in 1942 full on rationing limited not only the fabrics available but the styles of clothing. Every item was strictly regulated with even things like the number of buttons and pockets, and the sweep of the skirt limited to a set amount. To counter this, people became more creative with the limited resources they had available: Fair Isle became popular to use up small amounts of wool and bright accessories were used to cheer up the more limited colours of utility clothing. I wonder too if people used small bit of brightness to remind themselves of happier, pre-war times.
