This is a lovely PDF of a knitting pattern from the mid part of the 20th century- to help and instruct you how to knit and make wonderful 'Smog' hat helmets. A great talking point and we think when made up anyone would be happy to receive these from you as a knitted gift.
Smog/thick industrial fog was a big problem in the UK in the mid 20th century and this would assist the wearer to be able to protect their lungs from the pollution.
The suggested yarn is 3 ply and DK and the sizes range from babies/toddlers to adults.
