As far as I can tell, Jaeger yarns are no-longer commerically available, certainly not in Australia. Although you will find remnants of them on eBay, Etsy and other such marketplaces.
We have a selection of patterns, that given their age, are probably regarded as vintage. We present them here for your enjoyment.
Patterns in this category include:
Jumpers
Cardigans
Waistcoats
Monte Cristo was a standard 8ply with 22sts per 10cm square and 106m per 50g.
Matchmaker had the same tension as Monte Cristo but came in 50g balls with 120m
