Someone once asked me how I swapped blocks...
Here is the process I used to swap the sand stars.

First I laid out all the baggies, each bag a different person's stars.

I had piles on the kitchen table and on the porch table

Then I removed the stars from the baggies, and started swapping.

I swapped on both sofas,

and on the coffee table too. I had some supervision.

I carefully placed one star on each pile, being extra watchful not to give one person the same star twice.
And when I was finished, I laid out each person's stars, double-checking that there were no duplications.

Looked good to me, so I rebagged them, and got them ready for mailing.
