If you are making a lot of cards with the prick and stitch method it is well worth getting one of the purpose made pricking mats that will be sold by your favourite craft store. Pricking mats are usually made from compressed fibre, felt or polyurethane foam. The size will be around 9 x 6 inches (22 x 16 centimetres) and ½ inch (1 centimetre) thick.
A by-product of a prick and stitch design is the holes that the thread passes through. Some people regard them as an important part of the design that should show and others think that they are better minimised.
