How to fix cracks in a Fritz Hansen Ant chair?  

how is the repair going?
I am in a similar situation I have 6 that are cracked and you have given me hope so I am curious to see how far you have gotten
please fill me in

How would
you go about repairing a cracked bird's egg -- without changing the appearance of the egg ?
Adding an additional layer of new veneer across the cracked area, on both surfaces of the plywood and with the grain crossing the grain direction of the existing faces, would be the only reliable way to firm and strengthen the chair, in my opinion. Anything less would likely be a cosmetic repair only, rendering the chair a "look only" object.
