These earmuffs are inspired by my character, Trevor from my book "The Beckton Hauntings."

You may sell your makes using this pattern, but please credit me for the design/pattern.
I'd classify this as an "advanced beginner"pattern. Because it requires crocheting around a headband, which can be difficult at first if you've never done it before.

If you have issues, feel free to reach out, and I'll do my best to clarify for you.
Techniques you should be familiar with include:
magic ring/circle.
double crochet
single crochet
slip stitch
the mattress stitch for sewing the skulls to the headband.
