Tivaevae are quilts made by Cook Island women for ceremonial occasions. Quilting is thought to have been imported to the Islands by missionaries. The quilts are highly prized and are given as gifts with other finely made works on important occasions such as weddings and christenings. Khayamiya is a form of suspended tent decoration or portable textile screen used across North Africa and the Middle East. It is an art form distinctive to Egypt, where they are still sewn by hand in the Street of the Tentmakers (Sharia Khayamiya) in Cairo. Whilst Khayamiya resemble quilts, they typically possess a heavy back layer and fine top layer of appliqué, without a central insulating layer. Mola textiles are a distinct tradition created by the Kuna people of Panama and Colombia. They are famous for their bright colors and reverse appliqué techniques, which create designs with strong cultural and spiritual importance within the indigenous culture. Forms of animals, humans, or mythological figures are featured, with strong geometric designs in the voids around the main image. These textiles are not traditionally used as bedding, but use techniques common to the larger international quilting tradition. Molas have been very influential on modern quilting design. There are many traditional block designs and techniques that have been named. Log cabin quilts are pieced quilts featuring blocks made of strips of fabric, typically encircling a small centered square (traditionally a red square, symbolizing the hearth of the home), with light strips forming half the square and dark strips the other half. Dramatic contrast effects with light and dark fabrics are created by various layouts of the blocks when joined to form a quilt top. These different layout variations are often named; some layouts include Sunshine and Shadow, Straight Furrows, Streak of Lightning, and Barn Raising. Nine-Patch blocks are often the first blocks a child is taught to make. The block consists of three rows of three squares. A checkerboard effect with alternating dark and light squares is most commonly used. The Double Wedding Ring pattern first came to prominence during the Great Depression. The design consists of interlocking circles pieced with small arcs of fabric. The finished quilts are often given to commemorate marriages. Cathedral Windows is a type of block that features reverse appliqué using large amounts of folded muslin, and consists of modular blocks in an interlocking circular design that frame small squares or diamonds of colorful lightweight cotton. The volume of fabric is high, and the tops are heavy.
