Need to add a row to the Cheers squares to get the size of the Arthur squares. Planning to equalize to 39 stitches. Join with dark brown. All colors in border or just the browns and greens?

Considering flat braid join: https://www.ravelry.com/patterns/library/flat-braid-joini.... Like the idea of some space between the larger squares.

Probably join all the small ones much closer, maybe this method: https://attic24.typepad.com/weblog/joining-granny-sqaures....
