Embroidery stitches are the smallest units in embroidery. Embroidery patterns are formed by doing many embroidery stitches, either all the same or different ones, either following a counting chart on paper, following a design painted on the fabric or even working freehand. Heraldic Hand Stitched Embroidery uses various combinations of stitches. In Heraldic Hand Stitched Embroidery you find a special name to help identify it. These names vary from country to country and region to region. Some embroidery books will include name variations. Taken by themselves the stitches are mostly simple to execute, however when you put them together the results can be extremely complex. Heraldic Hand Stitched Embroidery work by needle. The needle is brought to the upside of the fabric. For doing the stitch properly, it is inserted into the fabric and brought back to the surface in one movement. Then the thread is pulled through. The same method is used for plain hand sewing. A thimble is usually used on the middle finger to avoid minor injury. Once the needle is inserted into the fabric, the hooded middle finger is used to push it through; the thumb and index finger grab the needle at the front as soon as possible and pull at the same time. This can speed up working when the embroiderer is used to it. This method can be done using an embroidery frame or free-hand, but usually an embroidery frame or hoop is used to make work easier. The technique uses frames that allow for adjustment of fabric tension, as the fabric can't be too strongly stretched.
