Knitted these on 3.5mm needles to get the larger size but they’re pretty roomy even for my large hands. Have steamed them to bring them down to size and relatively happy, though they could do with less room just above the wrist. If I was to knit them again I think I’d take out some stitches on the back of the mitt at that point, and increase between the wrist and the thumb. Otherwise lovely pattern, lovely wool and very glad I bought this wee book.
