Help - Biro on leather sofa.

[Arransmummy]

I know this has probably been asked before. I have got a brown leather sofa that my artistic 2 year old has drawn on with biro. I know he shouldn't have had it but I turned my back for 2 mins. Does anyone know how i can get it out without ruining my sofa?

Thanks

Hair spray - yes sounds daft but it does work!

If all fails you can buy a special remover. Furnature world does a leather care pack I think
