Wallpapering problem

[spoony77]

Hi people
I recently wallpapered a room in our house with black feature paper.
Unfortunately even though i was so careful to make sure the paper was touching when i mounted it - now it has dried i have white lines showing down the joins.
Any advice on what i can do to hide these?
Kind regards

In an earlier post i recomended to either paint some black emulsion on the walls roughly where the joins will coincide or you can get coloured crayons to rub over the edges of the paper prior to hanging. at the moment you cant do either !! You could try a dark felt tip pen.
