Drawing of a zigzag.

A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular.

Contents

In geometry, this pattern is described as a skew apeirogon. From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection.

Although the origin of the word is unclear, its first printed appearances were in French-language books and ephemera of the late 17th century. [1]

Quilting is the term given to the process of joining a minimum of three layers of fabric together either through stitching manually using a needle and thread, or mechanically with a sewing machine or specialised longarm quilting system. An array of stitches is passed through all layers of the fabric to create a three-dimensional padded surface. The three layers are typically referred to as the top fabric or quilt top, batting or insulating material, and the backing.

A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry.

<span class="mw-page-title-main">Chain stitch</span> Type of embroidery stitch

Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft – examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period. Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread.

<span class="mw-page-title-main">Mola (art form)</span>

The Mola or Molas is a hand-made textile that forms part of the traditional women's clothing of the indigenous Guna people from Panamá and Colombia, South America. Their clothing includes a patterned wrapped skirt (saburet), a red and yellow headscarf (musue), arm and leg beads (wini), a gold nose ring (olasu) and earrings in addition to the mola blouse (dulemor). Two groups, Choco and Cuna lived side by side without intermarriage and without adopting a similar culture. In Dulegaya, the Guna's native language, "mola" means "shirt" or "clothing". The mola originated with the tradition of Guna women painting their bodies with geometric designs, using available natural colors; at a certain point, after the arrival of the Spanish, these same designs were woven in cotton, and later still, sewn using cloth "acquired by trade from the ships that came to barter for coconuts during the 19th century".

<span class="mw-page-title-main">Warp knitting</span> Manufacturing process

Warp knitting is defined as a loop-forming process in which the yarn is fed into the knitting zone, parallel to the fabric selvage. It forms vertical loops in one course and then moves diagonally to knit the next course. Thus the yarns zigzag from side to side along the length of the fabric. Each stitch in a course is made by many different yarns. Each stitch in one wale is made by several different yarns.

<span class="mw-page-title-main">Knitted fabric</span> Textile material made using knitting techniques, often by machine knitting

Knitted fabric is a textile that results from knitting, the process of inter-looping of yarns or inter-meshing of loops. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats.

In sewing and dressmaking, a ruffle, frill, or furbelow is a strip of fabric, lace or ribbon tightly gathered or pleated on one edge and applied to a garment, bedding, or other textile as a form of trimming.

<span class="mw-page-title-main">Satin stitch</span> Flat embroidery stitch

In sewing and embroidery, a satin stitch or damask stitch is a series of flat stitches that are used to completely cover a section of the background fabric. Narrow rows of satin stitch can be executed on a standard sewing machine using a zigzag stitch or a special satin stitch foot.

<span class="mw-page-title-main">Gather (sewing)</span>

Gathering turns the edge of a piece of fabric into a bunch of small folds that are held together by a thread close to the edge. Gathering makes the fabric shorter where it is stitched. The whole of the fabric flares out into irregular, rolling folds beyond the gathered stitching. Gathering can be done by hand, with a machine, automatically, with elastic, or through channels.

<span class="mw-page-title-main">Bar tack</span>

In sewing, bar tack, also written bar-tack or bartack, refers to a series of stitches used to reinforce areas of a garment that may be subject to stress or additional wear. Typical areas for bar tack stitches include pocket openings, buttonholes, belt loops, the bottom of a fly opening, tucks, pleats and the corners of collars. Bar tacks may be sewn by hand, using whip stitches, or by machine, using zigzag stitches. The process for sewing a bar tack is essentially to sew several long, narrowly-spaced stitches along the line of the bar that will be formed, followed by short stitches made perpendicular to the long stitches, through the fabric and over the bar. The bar commonly varies between 116 to 18 inch in width and 14 to 38 inch in length. In some garments, such as jeans, the bar tack will be sewn in a contrasting color.

Sewing is the craft of fastening or attaching objects using stitches made with needle and thread. Sewing is one of the oldest of the textile arts, arising in the Paleolithic Era. Although usually associated with clothing and household linens, sewing is used in a variety of crafts and industries, including shoemaking, upholstery, sailmaking, bookbinding and the manufacturing of some kinds of sporting goods. Sewing is the fundamental process underlying a variety of textile arts and crafts, including embroidery, tapestry, quilting, appliqué and patchwork.

A zigzag stitch is variant geometry of the lockstitch. It is a back-and-forth stitch used where a straight stitch will not suffice, such as in reinforcing buttonholes, in stitching stretchable fabrics, and in temporarily joining two work pieces edge-to-edge.

<span class="mw-page-title-main">Blind stitch</span>

A blind stitch in sewing is a method of joining two pieces of fabric so that the stitch thread is invisible during the normal use of the finished product. Blind stitching uses a folded edge of the fabric to hide the stitches; therefore, this type of stitch can be used to create a blind hem or to join two folded edges together.

<span class="mw-page-title-main">Coverstitch</span> Kind of stitch

A coverstitch is formed by two or more needles which add straight stitches to the fabric and a looper thread on the opposite side of the fabric that zig-zags between the straight stitches. A coverstitch results in parallel lines of straight stitches on one side of the fabric and an overcast stitch on the reverse side. It is widely used in garment construction, particularly for attaching trims and flat seaming where the raw edges can be finished in the same operation as forming the seam.
