The free pattern is located on my blog/website at https://wp.me/pcladj-53

Materials:
6.00 mm hook
Size 4 (worsted weight) yarn (2 strands held together)
Yarns Used in this test: Heartland, Pound of Love, Mandala Ombre, 24/7 Cotton

Notes:
This is a one size fits all adult ear warmer. There are two patterns: one for regular tension and normal to bigger size 4 yarn, and one for tighter tension and thinner size 4 yarns.
It is a good idea to keep your tension loose so that your ear warmer is stretchier. It makes a huge difference to keep your slip stitches loose as well.
