I have started a pair of yoga socks to give as a gift. The feedback on the pattern on Ravelry is that they end up being a bit loose.
I'm about to start the heel portion so I have two options: 1) To continue as the pattern would like me to or 2) to go down a needle size or two so that the part that needs to be more fitted, is a bit more tight. I'm tempted to keep going on this one and see if the pattern instructions work out for me. The risk is that I finish and need to frog; then adjust and knit two more. Even with sleeves of garments I tend to get bored on the second one...hmmmm.
