what is the difference between needlepoint and petit point
Needlepoint The degree of detail in needlepoint depends on the thread count of the underlying mesh fabric. Needlepoint worked on fine canvas is known as petit point. Due to the inherent stiffness of needlepoint, common uses include eyeglass cases, holiday ornaments, pillows, purses, upholstery, and wall hangings.[citation needed]
Cartesian coordinate system A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis (plural axes) of the system, and the point where they meet is its origin, at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.
