The patterns say to use a 3 mm needle, but when I knitted a tension square, it soon became clear that 3 mm was too big. I don't do much knitting on very small needles, so I had to go and buy some needles in smaller sizes. I think I can use 2.5 mm for the main part and 2 mm for the ribbing. I'm told that needles smaller than 2 mm don't exist, so that will have to do. Now, which pattern to choose? I like the one with the cable, but I'm worried that with variegated wool and cables there will be too much going on. I think the other one would probably work better. I'm open to suggestions, here and at next week's craft group meeting.
