What can be placed under the paper for the drawing tasks? In the manual, the photographs show a yellow mat of some description?
It is recommended that for the drawing tasks you use a ‘smooth writing base that is not too hard or slippery’ (see p. 28 of the manual). For the photographs, we used a piece of yellow card underneath the drawing trail, which showed up well on the table. If card is to be used in this way, care should be taken that it is frequently checked and replaced if it becomes rough or indented. The table top mat should not be used for the drawing tasks.
