You will need old lamp; tracing paper; scissors; wallpaper; pencil; ruler; removable tape; double-sided tape; clear craft glue; decorative trim; scalpel.
ONE Remove old shade from lamp, leaving core intact. Wrap tracing paper around shade; trim to fit. Trim template join to form straight line from top to bottom.
TWO Lay wallpaper, design face up, on flat surface. Place template on wallpaper so motif is positioned as desired. Using a pencil and ruler, trace ends of template exactly. Add 3cm extra width to long sides of template to allow for overhang. Cut wallpaper.
THREE Secure template using removable tape. Using scissors, cut wallpaper just down to template every 2cm to form tabs.
FOUR Cut double-sided tape in half lengthways to make a thin strip; press on inside of shade, top and bottom. Remove protective strip from tape. Position wallpaper around shade and glue seam in place as straight as possible. Press tabs firmly to double-sided tape so they stick and hold in place.
FIVE Glue decorative trim to edge of lampshade. Cut trim to meet on joining seam of wallpaper. Using scalpel, trim exposed tabs on inside of shade to edge of trim.
TIP Add sequins to motifs for a 3D effect.
