With this interactive pattern you can make a contrasting color short row heel without the stripe on the instep. The secret sauce is one wrap and turn at each end of the instep needle which prevents holes from forming.
The afterthought heel is the ideal for colorwork socks or socks knitted with self-striping yarn. It can be used also for the perfectly symmetric contrasting color heel. It is made exactly the same way regardless if you start your sock from toe or cuff.
