From June 1941 clothing was rationed.
| Leftover balls of yarn in varied shades could be made into "Fairisle Patterns" either a simple toothed pattern as shown below or one of the more traditional Scottish patterns.|
Knitwear which needed resizing were given "fairisle" inserts where there was insufficient unpicked wool to complete the item in the original colour.Growing juveniles tend to need longer arms and trunk without necessarily increasing in girth.
Not every hooped or 'harlequin' jumper you will see was a wartime reknit but every one is a contender. Patterns with holes and lacy designs use less yarn than plain knitting.

Booklets & magazines gave tips for knitting from salvaged yarn but there were no patterns as such.
