Convertible Placemats and Table Runner

A convertible placemat, comprising:

• a perimeter shape defining at least a first side and a second side opposite the first side;
• wherein the first side includes a first complex edge pattern including multiple curved or non-parallel geometric features;
• wherein the second side includes a second complex edge pattern including multiple curved or non-parallel geometric features;
• and
• wherein the second complex edge pattern is geometrically complementary to the first complex edge pattern, such that the second complex edge pattern geometrically mates with the first complex edge pattern of a similar or identical placemat when the two placemats are arranged side-by-side with the second complex edge pattern abutting the first complex edge pattern.

A convertible placemat, comprising:

• a top surface having a three-dimensional surface texture defined by an array of interconnected three-dimensional structures;
• wherein each three-dimensional structure has a peak defined by a point or surface;
• and
• wherein the array of interconnected three-dimensional structures defines a plurality of valleys between two or more adjacent peaks;
• a bottom surface having a different surface texture than the three-dimensional surface texture of the top surface;
• and
• wherein, when the placemat is placed on a planar surface, a texture ratio of (a) a top surface texture variation measured from a particular peak to a particular adjacent valley in a direction normal to the planar surface to (b) a placemat thickness measured from the particular peak to the planar surface in the direction normal to the planar surface, is at least 25%.

A table runner comprising:

• a plurality of similarly shaped placemats arranged in a row and abutting each other side-by-side;
• wherein each placemat includes:
• a first side and having a first complex edge pattern including multiple curved or non-parallel geometric features, and
• a second side having a second complex edge pattern that is geometrically complementary to the first complex edge pattern of an adjacent abutting placemat in the row of placemats.
