A4 Coloured Overlays

Coloured overlays in A4 size can be preferable to the smaller, more convenient Reading Rulers in a number of cases, either where factors of age (elderly or young), dyspraxia, or other disability cause co-ordination problems which make it difficult to move a reading ruler down the page to track text; or when both hands are engaged while text or other representations are being followed. Common examples of this use of tinted overlays are sheet music and knitting or other machining patterns. Overlays can easily be cut in half to use with smaller pages.
