To glue the paper from spreading the sheets perfectly vertical do not trust the references of a corner or a window but always draw a reference using the plumb line to maintain a perfect verticality.

When you get near a corner, proceed as follows:

• Measure down, halfway and top the distance between the last sheet laid and the corner or corner

• Take this measurement and add 2.5 / 3 cm. It will be the width of the cloth you need.

• Glue it making sure that it adheres well with the brush

• If the paper tends to wrinkle in the corner after the fold, make small horizontal cuts with a pair of scissors.
