Paint the wall with the base coat of Cashmere Blue Bells.
Start on the left-hand side of the wall and mark out the first stripe with the pencil and ruler. Continue along the wall, marking out all the stripes.
Using your pencil markings, draw in the stripes using the ruler. Use the spirit level to check that your stripes are straight.
Mask out the blue stripes (on the wall that has just been painted in Blue Bells) with masking tape.
Use the small sponge roller to fill in the green stripes. (We used Aqua Pool.) Leave to dry.
Pull off all the masking tape.
To finish off, mask off bands of two stripes at a time (cover one blue and one green stripe with masking tape) for the glossy stripes. Use the small sponge roller and fill in the glossy stripes with Plascon Glaze Coat.
