Here is a free basic beginner generic sock pattern for toe-up socks, one– or two-at-a-time, using Magic Loop and the Fleegle Heel. Following Fleegle's famous sock formula, written out in my own words. Design your own socks in any size, for any weight or gauge of yarn.
You can make a pair of toe-up socks in any size (baby to very large adult) in any weight of yarn (fingering to super-bulky) using this simple, generic pattern.
You just have to have the feet nearby to refer to, or at least be able to estimate the length of the foot from toe to front-of-ankle.
You can make these socks as a gift by comparing the recipient's shoe size against your own shoe size, and making the necessary measurements from there.
Links to abbreviation videos and special techniques included, as always. Enjoy!
