This is a pattern I stumbled across and have witnessed reduced patterns for years. It wasn’t until I produced one that had a face on it that I started examining the pattern and figuring out what it was.
This pattern is almost a negative of my extreme snowflakes. White in-between the crossbars where it is green on a snowflakes. White coming up the sides from the yellow. Where it is normally green on my snowflakes. Green around the crossbars while that is were all the white is on my snowflakes. I have also seen a couple basins over the years that had both alien and extreme snowflake patterns mixed. Maybe we will see that more in the future.
