Abstract: An improved sketching device is disclosed having a substantially flat base and a regular grid of at least 20×20 bumps disposed on the base. A bottom of the each of the bumps can be spaced apart from a bottom of an adjacent bump by a first distance comprising between 0.005-5 mm. The raised bumps can be sized and positioned to form a plurality of intersecting grooves.

Abstract: A kit for guiding a user is drawing a trace includes a sketching device coupled to a paper tablet. The sketching device comprises a first pattern of raised bumps sized and positioned to form a plurality of intersecting grooves along the surface of the sketching device.

Abstract: 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.
