How can I stop the print/dye from a dark (brown) wallpaper from scuffing off the edges .When the paper is hung you can see no joints between drops but when it is drying you can see the joints quite badly. The paper has a coloured edge to it but it still shows as a very visible white line when dry. Is there any way to stop this? I have thought of sealing the edge before hanging with a weak pva mix but this would be very time consuming and I dont know if this would cause more problems if paste gets onto it. Any help most appreciated.
