I am always looking for visual ways to communicate the properties of perspective drawing to my students. In a one-point perspective drawing, the furniture piece will have a flat front and the sides of the piece will be drawn using the single vanishing point and perspective guide lines. The pattern of the material on the flat front is to scale meaning there is not any perspective distortion. The sides and top of the ottoman fabric pattern uses the perspective guide lines.
When drawing case goods it is important to get the legs drawn correctly using the perspective guide lines. Depending on where the location of the piece is to the vanishing point will determine what side of the piece will be seen. Notice in the table to the left will show the right side of the legs and the table on the right will show the left side of the legs. Want to learn more about drawing furniture in perspective?
