Blanket, Squares.

I found this pattern easy to follow.
I blocked each square before joining them. And I decide to use the a flat braid join (Instructions HERE for the join).
For the border I just did 1 round of sc (after the flat braid set up) in white and a second round of hdc in dark blue.

 

The pattern is free HERE.
