Thanks guys I didn't realise that a piece of wood could be so dangerous! So I dyed it with a brown stain and black ink jet ink on top, invisible (ish) mending at its best!

Just got to get rid of the black ink of my fingers now! Tried everything, meths, acetone, cellulose, WD40 even tried Trichloroethane 111, there is no quick way of getting rid of ink jet ink off skin! I'll just have to wait until my skin cells regenerate!
