1950s 'Youngsters Woolies' pattern booklet
It is part of a twinset with the cardigan (bottom), is worked in two colours and has a lacey stripe patterned yoke. Did I mention this was my first ever knit garment?
Another funny flash-face
As it turned out, the pattern wasn't too difficult to knit: the holes are done by simply knitting stiches together. The only problems I encountered were of my own making, usually by miscounting and generally not paying attention.
