Hi, I was wondering if anybody could explain steps 5 and 6 of this model to me.

I don't understand what step five is at all, and I can't move on without it.
Thanks for your help in advance,

Step 5: there are two hidden corners inside the fox. They're the ones marked 'a' and 'b' in step 1. Fold them to the right edge of the fox.

Step 6: there are two things to do here. The diagonal fold on the left (marked 'narrow') is a simple valley fold through all of the layers. The right side is a spread-squash.

Thank you very much Joseph.
I know it's only a simple diagram but I somehow managed to get stuck.
With your help I've got it finished, now I can start learning how to do it without the diagram.
Thanks again, and I do love your work.
Keep folding.
