Since creating and naming this pattern, the author of said book has used her popularity and money to harass, demonize, and restrict the rights of trans people.
I am in the process of renaming this pattern, but in the meantime…trans and nonbinary people are valid as the humans they are, and the genders they know themselves to be.
TERFS are evil.

Evanesco: A spell used to vanish objects, at least in a series of books featuring a boy wizard and his friends.

I can’t promise these socks will actually vanish, but they will be much less visible in sneakers or other shoes; perfect for when you don’t want your socks showing.*

This sock recipe contains instructions for making a basic toe-up sock, and includes my variation on an afterthought heel with gusset and heel flap.
The construction of the heel fits well even with high insteps, and has the advantage of a super-comfortable heel cup with absolutely no wrap/turn short-row stitches.
There is an optional heel tab that includes a few short rows.
The pattern includes instructions for heavy worsted weight or fingering weight, and details for changing the size for a custom fit.

Gauge:
Heavy Worsted: 5.5 stitches and 8 rows per inch
Fingering: 9 stitches and 11 rows per inch

Techniques:

• Magic Loop
• JMCO (Judy’s Magic Cast-on)
• Left and Right Lifted Increases
• Afterthought Heel
• SSK
• P2tog
• Wrap and Turn

Materials:
* 100g sock yarn (Socks pictured:
Worsted, Novita 7 Brothers; Fingering,

* 40” Circular Needle. Worsted, size US
6 (4.0mm) Fingering, size US 1
(2.25mm)

My test socks used 51g of yarn for fingering, in a man’s size 10.5, and 97g of worsted in a woman’s size 11.
