When I knit my seamless slippers (see pattern to the right), I repeat the increase row one more time. I like my slippers taller. Unfortunately this makes more stitches around the ribbed part of the toe area. I noticed this weekend that my toes were swimming inside my slippers. I think this is why I stopped making these for myself.
In the future I will decrease at least one or three stitches when I get to the ribbing so the slipper hugs my toes better.
I won’t call this errata as it is a personal preference.
