Embroidery is the art or handicraft of decorating fabric or other materials with needle and thread or yarn. Embroidery may also incorporate other materials such as metal strips, pearls, beads, quills, and sequins.

A characteristic of embroidery is that the basic techniques or stitches of the earliest work—chain stitch, buttonhole or blanket stitch, running stitch, satin stitch, cross stitch—remain the fundamental techniques of hand embroidery today.

Machine embroidery, arising in the early stages of the Industrial Revolution, mimics hand embroidery, especially in the use of chain stitches, but the "satin stitch" and hemming stitches of machine work rely on the use of multiple threads and resemble hand work in their appearance, not their construction.

[edit] Origins

The origins of embroidery are lost in time, but examples survive from ancient Egypt, Iron Age Northern Europe and Zhou Dynasty China. Examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th-3rd century BC).[1]

The process used to tailor, patch, mend and reinforce cloth fostered the development of sewing techniques, and the decorative possibilities of sewing led to the art of embroidery.[2] In a garment from Migration period Sweden, roughly 300–700 CE, the edges of bands of trimming are reinforced with running stitch, back stitch, stem stitch, tailor's buttonhole stitch, and whipstitching, but it is uncertain whether this work simply reinforces the seams or should be interpreted as decorative embroidery.[3]

The remarkable stability of basic embroidery stitches has been noted:

It is a striking fact that in the development of embroidery ... there are no changes of materials or techniques which can be felt or interpreted as advances from a primitive to a later, more refined stage. On the other hand, we often find in early works a technical accomplishment and high standard of craftsmanship rarely attained in later times. [4]

Elaborately embroidered clothing, religious objects, and household items have been a mark of wealth and status in many cultures including ancient Persia, India, China, Japan, Byzantium, and medieval and Baroque Europe. Traditional folk techniques are passed from generation to generation in cultures as diverse as northern Vietnam, Mexico, and eastern Europe. Professional workshops and guilds arose in medieval England. The output of these workshops, called Opus Anglicanum or "English work," was famous throughout Europe.[5] The manufacture of machine-made embroideries in St. Gallen in eastern Switzerland flourished in the latter half of the 19th century.

[edit] Classification

Japanese free embroidery in silk and metal threads, contemporary.

Embroidery can be classified according to whether the design is stitched on top of or through the foundation fabric, and by the relationship of stitch placement to the fabric.

In free embroidery, designs are applied without regard to the weave of the underlying fabric. Examples include crewel and traditional Chinese and Japanese embroidery.

Cross-stitch counted-thread embroidery. Tea-cloth, Hungary, mid-20th century

Counted-thread embroidery patterns are created by making stitches over a predetermined number of threads in the foundation fabric. Counted-thread embroidery is more easily worked on an even-weave foundation fabric such as embroidery canvas, aida cloth, or specially woven cotton and linen fabrics although non-evenweave linen is used as well. Examples include needlepoint and some forms of blackwork embroidery.

Hardanger, a whitework technique. Contemporary.

In canvas work threads are stitched through a fabric mesh to create a dense pattern that completely covers the foundation fabric. Traditional canvas work such as bargello is a counted-thread technique.[6] Since the 19th century, printed and hand painted canvases where the painted or printed image serves as color-guide have eliminated the need for counting threads. These are particularly suited to pictorial rather than geometric designs deriving from the Berlin wool work craze of the early 19th century.[7][8][9]

In drawn thread work and cutwork, the foundation fabric is deformed or cut away to create holes that are then embellished with embroidery, often with thread in the same color as the foundation fabric. These techniques are the progenitors of needlelace. When created in white thread on white linen or cotton, this work is collectively referred to as whitework.[10]

[edit] Materials

Phulkari from the Punjab region of India. Phulkari embroidery, popular since at least the 15th century, is traditionally done on hand-spun cotton cloth with simple darning stitches using silk floss.
Laid threads, a surface technique in wool on linen. The Bayeux Tapestry, 11th century.

The fabrics and yarns used in traditional embroidery vary from place to place. Wool, linen, and silk have been in use for thousands of years for both fabric and yarn. Today, embroidery thread is manufactured in cotton, rayon, and novelty yarns as well as in traditional wool, linen, and silk. Ribbon embroidery uses narrow ribbon in silk or silk/organza blend ribbon, most commonly to create floral motifs.[11]

Surface embroidery techniques such as chain stitch and couching or laid-work are the most economical of expensive yarns; couching is generally used for goldwork. Canvas work techniques, in which large amounts of yarn are buried on the back of the work, use more materials but provide a sturdier and more substantial finished textile.[9]

In both canvas work and surface embroidery an embroidery hoop or frame can be used to stretch the material and ensure even stitching tension that prevents pattern distortion. Modern canvas work tends to follow very symmetrical counted stitching patterns with designs developing from repetition of one or only a few similar stitches in a variety of thread hues. Many forms of surface embroidery, by contrast, are distinguished by a wide range of different stitching patterns used in a single piece of work.[12]

[edit] Machine

Commercial machine embroidery in chain stitch on a voile curtain, China, early 21st century.

Much contemporary embroidery is stitched with a computerized embroidery machine using patterns "digitized" with embroidery software. In machine embroidery, different types of "fills" add texture and design to the finished work. Machine embroidery is used to add logos and monograms to business shirts or jackets, gifts, and team apparel as well as to decorate household linens, draperies, and decorator fabrics that mimic the elaborate hand embroidery of the past.

The idea behind the keyboard shortcuts in Adobe® Illustrator®, Adobe Photoshop® and Macromedia® FreeHand® is so you can draw paths in a fluid manner with as few interruptions as possible. Ideally, you would draw as fluidly as if you were actually using a pen or pencil. The previous page described the hand positions with the keyboard and mouse. This page describes how it is done. The next page gives you practice templates for each application.

While the pen tool is selected and you are actively drawing a path, pressing the following keys will bring up a different tool:

For Adobe Illustrator or Adobe Photoshop:

Macintosh® Windows® Function
Command
Option
Shift
Ctrl
Alt
Shift
Selects the last selection tool
Selects the Convert Direction Point Tool
Constrains angle to 45° increments

For Macromedia FreeHand:

Macintosh Windows Function
Command
Option
Shift
Ctrl
Alt
Shift
Selects the Pointer Tool
Places a corner point
Constrains angle to 45° increments

Basically the functions of these keys between the Adobe applications and Macromedia FreeHand are the same. There is only a slight difference in the use of the Alt or Option key to create a corner point. In Illustrator and Photoshop, all newly placed points with control handles are smooth points by default. The Convert Direction Point Tool is used to change a smooth point to a corner point with handles. In FreeHand, you can drag out control handles for a corner point when you first place it.

Brief Example - Adobe Illustrator

In the following example, three tools are used without returning to the tool palette to change tools:
1. Drag out the first point
clover1a.gif

2. Drag out the second point. The first curve is off, now. clover2a.gif

3. Press Ctrl (Windows) or Command (Macintosh) and use the Direct Selection Tool to drag back the first curve. clover3a.gif

4. Press Alt (Windows) or Option (Macintosh) to bring up the Convert Direction Point Tool and drag the second point's handle (changing it from a smooth point to a corner point) to redirect the next curve. clover4a.gif

5. Place the next point and continue drawing the path. clover5a.gif

Pen Cursors

The pen cursor helps you identify where you're at when drawing paths. You need to know when you are over a point so you can append to an open path (restarting the path) or when you are over a point so you can close a path. You also need to know what the cursor looks like to start a new path so you don't inadvertently keep adding to an existing path or vice versa. These are the most important cursors. Their functions are identical between Adobe Illustrator 7 and 8, Adobe Photoshop 5 and Macromedia FreeHand 8. The chart below describes these cursors.

Draw Faster By Making Fewer Trips To The Tool Palette

This tutorial is for applications that use the pen: Adobe® Photoshop®, Adobe Illustrator® and Macromedia® FreeHand®. When drawing with the pen you will inevitably have to stop mid-path and make adjustments to anchor points, control handles or line segments.

postit.gif Note: Different software packages use different terms for the same things, and since this article is using mixed terminology please consult the table of equivalent terminology for clarification of terms.

Usually, when first learning the software, the novice will go to the tool palette to switch back and forth between the pen and other tools. This is very time consuming and there are provisions in the software to switch tools without having to select them from the tool palette. The keys on both the right-hand and left-hand sides of the spacebar are used for this purpose. Shown below are the keyboard hand positions for a right-handed mouse:

Left hand keys - Windows®

Left hand keys - Macintosh®

Shift =
Alt =
Ctrl =

Shift
Option
Command

keyswin.gif keysmac.gif
handkeys.gif

The diagram above shows the hand positions (for a right handed mouse) to take advantage of keyboard shortcuts for drawing with the pen. This is the quickest way to use the pen.

Mac® users will use various combinations of the Shift, Option and Command keys, while Windows users will use parallel combinations of the Shift, Ctrl and Alt keys.

For example, while actively drawing a path with the pen tool, Windows Illustrator users can press the Ctrl key to switch between the pen and the selection tool while at the same time press the Shift key to constrain a line to 45° increments. When finished making the adjustment, the user simply releases the keys and resumes drawing with the pen tool - all without resorting to the tool palette.

Following this tutorial are step by step examples to drill the point.
