Ok I have cast back on and started paying lots more attention to what I'm doing.
First on the right hand side is a blue stitch marker. That denotes (for me) my starting of my sock and also that this is the first sock knit on or sock #1(see angled arrow).
And on the left side (see straight arrow) that shows the sock I am working on at the moment by being on the needle. That way I know which sock to work on when I pick it up again.
And the little white stars mark the chicken stitchmarkers that I am using to show myself the middle of each sock so later on I won't have to count out the stitches.
What are you all doing to keep things straight in your heads?
