ditto to what others said .... you'll get there with the familiarity thing on these blocks!!
Some blocks get confusing, as there are several different names for the same block.
As far as I know SAS (Storm At Sea) only has one name.
However, with that being said, with different colour placements,
SAS can have many different looks, and can be easily not recognized.
Kind of like a chameleon!!
Here's one that I did ... with a Christmas twist!
