Sketching Device for Copy Paper |
摘要 |
Apparatus and methods for facilitating writing on copy paper are presented. A sketching device can be inserted between upper and lower sets of copy paper to facilitate writing or sketching on the upper set while acting as a barrier to prevent undesired imprinting of the writing or sketching on the lower set. Preferred sketching devices include a physical pen guide that acts as a tactile guide for a drawing instrument. The sketching device can be included for use with a form having a grid, and can itself include a preprinted surface having character designations that indicate different types of information on x and y axes.
