My boyfriend wanted a small skull pattern and here it is

Overlay mosaic method
(1 color/row, cut yarn at the end of the row)

Chart only!!!!! (with X marked)
(81 sts pattern + 2 border sts wide and 94 rows)

The size depends on the yarn and hook you use

If you want to add a border I suggest to use Rosina Planes “Easy Envelope Borders”:

Anchored sts (no gaps on ws): https://www.youtube.com/watch?v=UfRvfdCPeFE&t=62s
