Many sweater knitting patterns suggest an even rate of decreases from just below the armhole to just above the wrist. On close-fitting garments, that often makes the sleeves too tight for me around the biceps. Instead I tend to knit straight until just above the elbow and only then start decreasing.

That bit worked well this time, as expected, but I wasn’t happy with the decrease rate afterwards. Too steep. Rip it up and do it again.

With a slightly thicker yarn and a slightly looser knit than I generally tend to choose, the cardigan almost knits itself. And when I change my mind, unravelling and re-doing a section is a piece of cake. With loose-ish stitches, there’s room for me to insert a thin cable needle in a row further down in advance, before I even start ripping it up. No need to painstakingly find and pick up the stitches afterwards. Re-knitting it takes an hour at most.
