Forethought Heel Sock Calculator

This tool creates a custom pattern for a forethought‑heel sock. You’ll knit a plain tube in the round, place a row of placeholder yarn where the heel will go, and later work both the toe and heel using classic wedge shaping.

For a yarn‑amount guidance, see the Yarn Amount Estimator
