Quilt Notes: TRIANGULAR TRIANGLE, a four-patch block, is illustrated in Maggie Malone's 5,500 Quilt Block Designs (Sterling, 2004, without templates): the illustration right reverses the standard light background to black. Malone credits the design to the Ladies Art Company, which began publishing quilt patterns in the late 19th century. The design has an exquisite mathematical beauty and seems to work well with a precise fabric print and clear solids, or with the counterpoint of stained fabrics or batiks.
