Have your design enlarged to scale at a copy shop. Using spray adhesive, attach the enlargement to stencil board. With the craft knife, cut the stencil from the board – use a ruler to get the lines straight.
Paint the wall in the base colour: we used Mystic Tulip (R1-A1-1). Allow it to dry, then, using the tape measure, measure a distance twice the width of your stencil from the floor. Use the spirit level and draw a line at this height, mark it with the chalk and mask with tape. In the same way, draw another chalk line halfway between the floor and the top line.
Place two corners of the stencil on the central line and, using chalk, trace the pattern. Using chalk and the spirit level, create panels above and below the design, then mask them with tape. Paint your colours into the unmasked areas using the large sponge roller and paint tray, and between the stencil lines using the small sponge roller and paint tray.
Once dry, using the spirit level, chalk and tape, create a narrow panel above the top band of tape before painting in the colour with the small roller. Remove the masking tape when all the paint has dried.
