Thread: How to bend sheet timber

G'day.
I am going to make a timber panel which I will then make a resin mould out of for casting a resin copies of the timber original.
I need to bend a panel of timber with dimensions 1.8m high by 1m wide (by 5 or 6mm), so that the two sides become 90 degrees to each other.
The panel will need to have a timber framework attached to the back afterwards.
I guess that Timber would be the only thing I could use (unless anyone can suggest
a material about 5mm thick that will bend and then hold its shape?).
If timber; what should I use and how would I bend it.
Thanks
