If the ceiling is in good condition, size the surface and leave it to dry before papering. If the Plaster is uneven, line the ceiling first for the best result. As with walls, always hang lining paper at right-angles to the decorative covering so the joins do not coincide.
Hang ceiling paper parallel to the main window in the room so the joins are not too noticeable. Measure the width of the paper, deduct 6mm for turning onto the end wall and mark this distance in pencil at both sides of the ceiling. Chalk a length of string and fix it at one side with a drawing pin. Stretch the string between the two pencil marks and pluck it so the chalk is transferred to the ceiling. Cut the number of lengths required, allowing for the pattern to match and for trimming at both ends. Paste and fold each length concertina-fashion as for lining paper. Hang the first length flush against the chalk line. Unfold the last pleat and smooth it onto the ceiling. Release the paper one pleat at a time, supporting the rest of the Paper with a spare roll. Brush out each section onto the ceiling. Turn 6mm onto the end and side walls then trim and sponge away any surplus paste. Hang the other lengths in the same way, butt-joining the edges and turning 6mm onto both side walls. Remember to allow 6mm in the width of the last length for turning onto the end wall. At a ceiling light, make star-shaped cuts as for projecting light switches. Smooth paper round fitting and trim flaps.
