hi all. seem to keep having the same prob with paste the wall paper. So... I strip existing paper,,,line the wall... then put up this ptw paper ...as it happens I paste the paper as opposed to the wall and hang it. Then next day the seems seem to show !! What am I doing wrong ? Is the lining soaking the paste therefore top paper shrinking or am I wrong to paste the paper as opposed to the wall ? Help me !!!!
