Needles
Needle refers to a small, slender piece of steel with a hole for thread and a point for stitching fabric. A machine needle differs from a handwork needle; the machine needle's eye is found at its pointed end. Machine embroidery needles come with sharp points for piercing heavy, tightly woven fabrics; ball points, which glide between the fibers of knits; and a variety of specialty points, such as wedge points, which are used for leather. In contrast beading needles are very thin and their eyes are the same width as the rest of the needle. This provides with an added advantage of no added metal width to get in the way as it pass through seed and other small-holed beads. These needles also come in a twin-pointed version that are used for bead embroidery and a glover's version which have a triangle tip used for leather bead embroidery. Big Eye needles are extremely easy to thread. They feature two sharp ends with tension wires down the middle that can be split; simply open the wires and pass the thread through. Twisted beading needles are primarily used for stringing beads because they don't have a sharp point and their wide eyes are easy to thread.
