First, make 3 piggies on each side.
I started with the top right & braided it.
Take it across, over to the top left. Add your elastic.
Braid the top left & cross it down to the middle right, add your elastic. Then braid that & cross it over to the middle left. See the pattern - you are making a zig-zag pattern. But stop there.
Now, go to your bottom left & braid that.
Cross it over to the bottom right & add your elastic.
