I chose to play safe and knit for myself, and this darker yarn to start with as it will hide mistakes I might make along the way, but surprisingly there were no laddering and the much talked about 'gap' between the heel, cuff and instep does not exist. (small pat on the shoulders)
I learnt that, 'for the majority of us, the foot is exactly the length of your forearm from the base of your palm to the inside of your elbow'. Phew! what a relief. Isn't it much easier and polite to measure the hand rather then for someone to turn his/her foot out for measurements? It could be rather annoying when one is in need of a shower too!
And the length of our foot is about equal to the circumference at the widest part. All this trivia from sock knitting!
I believe God created us and all these 'coincidences' are not chance and evolution. Sock making made easy - because God is a great designer!
