A thin strip of material is provided with a substantially smooth upper surface to accommodate the movement of a marking instrument, such as a ballpoint pen, thereacross to form the starting or ending of the drafting of a line. The guide edge of the strip is such as to allow smooth movement of the pen between said strip and said drawing surface and an ink-receptive covering is provided on the strip to remove excess ink whereby the end of each line is uniform. The strip is flexible plastic having a plurality of apertures formed therein and the covering is formed of masking tape with the sticky side extending through the apertures to temporarily fix the strip to the drawing surface. The depressions in the tape formed at the apertures allow more efficient cleaning of the sides of the pen when rotated.
