Answer
You need pasting table, bucket of paste (polycell is nice), brush to apply paste, straight rule wood or metal, sharp scissors or knife and a clean towel.i always start on the corner left of the window and work to the right. make sure that the wall is straight, you need a plumb-bob a long piece of string with a weight tied to it.measure the drop from ceiling to skirting add 6ins to the paper to give you a 3in leeway at each end. before you cut your paper select two rolls it is easier to match patterns by you using 2 rolls. so you will now have your 1st run of paperfrom roll 1, cut your second piece from roll 2, 3rd from roll 1, 4th roll 2 and so on.now comes the important bit lay the paper pattern down onto the table with the top to your left, liberaly add paste to paper ensuring that you put plenty on the top, sides and bottom. so that you do not drop or tread on the paper between table and wall fold it back on itself paste to paste. you will then have a smaller piece to take up the steps/ladder to your start position.you may have to put some paste onto the wall if it is absorbant. picking up the paper by the top place it on the wall then tease the folds out until the paper is roughly where it should be hung.using the towel smooth out the excess paste,bubbles, wrinkles from the paper using a herringbone pattern. if you need to move the paper in any direction always pull it from the bottom upwards.when you are satisfied that it is how it should be cut your second piece of paper from the 2nd roll and proceed as with the first piece. by using 2 rolls together the waste will be about 6inches per piece cut but if you use only 1 roll you lose about a yard between pieces.you will have to use a sponge or another towel to keep the paste table clean you do not wanna get paste on the pattern side of the paper.final job, will be to trim the paper top and bottom usually best done when it #is semi-dry as wet paper has a nasty habit of cutting jagged. if the paper comes away it is easy to add some paste and towel it back in place.nice luck
