My first attempt at boot cuffs didn't turn out so well (despite following the pattern), so I gave it another try, with some adjustments. For any knitters out there that are curious what I did - I followed this pattern, but only cast on 44 stitches (instead of the 74 in the pattern) and used #7 needles, instead of #8. They fit quite snug, so it might be good to add on a few more stitches (or maybe stick with the #8 needles). Still, I'm quite happy with how they turned out.
I've worn them both dressed up and dressed down, although I think I like the casual look better.
