I'm knitting socks for an aunt, but I'm a little anxious- I don't have her ankles handy to measure. The socks look a little wide to me as I work down from the top. They're 3.5" across, so 7" around. That would work for socks for me, but is it likely to work well for other people? (I'm knitting with the KnitPicks bare merino which seems to be nice and stretchy.)
Can someone please reassure me?
