The red and yellow hacky sack at the front center of the photo is obviously the swirly one. So cool looking.

Such an intense pattern. Not hard, but clever. It requires brain power and is time consuming (at least for me) to make. Her increases and stitch counts are different from the others, but still ended up the same size.

I watched the YT video -- very helpful, and I used scraps and stash.

Designer says to use a nylon 2x the size of the ball.
