CROCHET: Wendy Festival Throw is now a square

Do i keep the square of 7 x 7 squares or make it rectangular and bigger still maybe 7 x  9 squares and spend another day making squares?

Then to add a border...triangles with a border or a straight border?

I liked the idea of triangles but not so pleased with how they actually looked after doing several...more thought needed.

the 6 colours of yarn I am using in this throw

6mm hook and its beautiful to work with, soft and cosy when made up
