I need help with four leaf clover by gerwin sturm, step 12

http://www.origamiaustria.at/diagrams.php?lang=2

Here's step 12 in slow mo...

First off, make sure all the layers are distributed evenly like so...



Then pre-crease the 3 sides you want to sink.



Next, turn the model over and adjust 2 of the leaves and move them downward so you can see the back part of the model like so...



What the model looks like after...



We do this so we can get a finger or two inside the now exposed flap to open sink.



and like so...



With our fingers we spread out the flap like so which is a step towards open sinking the flap like so. The rest of the model partially unfolds.



We then bring the sides in like so to complete the open sink.



Readjust the model so the folds fall back into place and the model looks like this.



After that just fix the leaves so they are in the position you started with...



And the model looks like this from the back after you finish 1/3rd of the step. (since you have 2 more flaps to open sink)




Rinse, and repeat on the other 2 sides.

Hope this helps!
