Use high-density sponge for sharply defined and detailed designs. Trace your chosen motif on to the sponge using a soft pencil for dark, clear lines.
Cut along the outline using a sharp blade, then, pinching the background sections, cut them away holding the blade away from your fingers.
Roughly cut around the design, then spray the tracing paper with adhesive to hold it in place on the sponge while you are cutting it out.
When using a stamp mounted on a block, draw a straight line on the back to help with positioning. Align the block with the pencil guideline on the wall. A piece of cardboard held between the previous print and the stamp will ensure consistent spacing between motifs.
Sharp scissors, rather than a blade, can be used with medium-to-low density sponge and are especially useful for cutting out the basic shapes.
PLANNING A DESIGN
With the aid of a spirit level (carpenter’s level), draw a faint pencil line to use as a guide when stamping. Once the stamping is finished and the paint is dry, this guideline can be removed using a cloth wrung out in soapy water and rubbed along the line.
Although stamping is sometimes thought of as another form of stencilling it is essentially a form of printing. You can achieve many way it is applied.
Half-shade: Roll the first, paler colour over the stamp, then roll a second, darker shade over one half only, to create a three-dimensional shadowed effect.
Sponge print: Applying the paint with a sponge gives variable, individual prints.
Two-tone: Using a dry roller, load the stamp with the first colour, then apply the second to the top and bottom edges only.
Stippled: This stippled effect gives the print lots of surface interest: apply the paint with a stiff brush and a dabbing, stippling motion.
Light shadow: The paint has been applied with a roller, covering each element of the motif more heavily on one side to create a delicate shadow effect.
Contrasting detail: Pick out details of the design in a contrasting colour: apply the first colour with a roller, and then use a brush to apply the second colour in the areas you want.
