#1 Rainbow scrappy:
. No chains between clusters, 1 or 2 chains in corners.
. Ended with a round of hdc clusters instead of dc to stop it from growing so much.
. 12 rounds total.

#2 Neutral stripes (ivory, brown, green)
. 2 chains in every corner.
. Ended with a round of sc clusters instead of dc or hdc.
. 12 rounds total.

NOTE: Whipstitch join through outer loops.

Raveler Mamaw227 had a brilliant idea to add a french knot through the centers to join them. Here’s her project: https://www.ravelry.com/projects/Mamaw227/granny-square-h...

I tried multiple methods to avoid having a super long tail at the end. I concluded that it’s not worth the extra stress/energy to mess with it, so the last time, my trick was to start in a corner, not the center, to finish two sides, then weave the way through to an opposite corner to finish the other two sides.
