when hanging grass cloth wallpaper i found that if it gets wet it tends to run or stain the color. what is the best way to hang colored grass cloth (red). should i glue the walls and then put up the grass cloth or just be careful when i glue the back then book it. also, should i trim the edges ( the instructions said you could ) they seem nice and straight to me. please send me some good advice. i am a wallpaper hanger by trade and have gotten several calls for this. i would like to keep up my good reputation by doing a good job for my client .. thank you, terry
