A vintage knitting pattern for His and Hers casual zipper jacket with instructions to knit in 6 sizes.
To fit bust/chest: 32" - 42".
Originally knitted using Lister Lee Target Can-Can yarn with a tension of 8 sts and 14 rows to 2" (5cm), using no. 3 (6.5mm) needles. I believe this yarn was a chunky weight yarn.
For success you should work a tension piece with your substitute yarn.
The pattern leaflet is in good condition.
