When I first learned to knit as a youngster I remember thinking that 4mm (US size 6) needles were oh so thin and therefore slow to knit with. Similarly DK yarn was a pain and I much preferred the speed of larger needles and chunky yarns.
How times have changed!
Now I prefer to knit with 4ply (fingering weight) yarn and I feel that 4mm needles are large and cumbersome.
Who would have thought it?
Stay safe and happy crafting
