The most common American pieced quilt format is the block style, composed of pieced design units (“blocks”) that are generally placed in a grid. The standard is a 90-degree grid but the blocks can also be placed “on point,” in a grid that has been turned 45 degrees so that rows run diagonally across the surface of the quilt. Usually, it is immediately apparent which grid style a quilt uses, but it can sometimes be tricky to determine if a quilt conforms to a 90-degree or 45-degree configuration. Depending on color and value placement and the pieced design itself, a standard grid placement can actually look like an on point grid, and vice versa. The key is to identify an individual block unit and determine its orientation. The other blocks will follow in its direction. See if you can tell which of these quilts are standard and which are on point.
