Now that you've learned to fold compound open and closed squares, it's time to add rectangles to the repertoire!

If you haven't learned them already, I recommend checking out my Hybrid Square Twist tutorial, Odd Division Grids tutorial, Open Compound Square Twist tutorial, and general Compound Squares tutorial before attempting this tessellation.
I start with a 40-fold square grid (instructions here), and walk you through the process of folding this tessellation, giving some ideas for variations as I go.
If you're ready, let's dive in!
As always, I'd love to see what you fold - tag me (@gatheringfolds) on Instagram to show off what you've made!
