Needlework in the context of "Crochet hook"

Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses (referred to as "weights"). Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue.

Embroidery thread is yarn that is manufactured or hand-spun specifically for embroidery and other forms of needlework. Embroidery thread often differs widely, coming in many different fiber types, colors and weights.

Opus Anglicanum or English work is fine needlework of Medieval England done for ecclesiastical or secular use on clothing, hangings or other textiles, often using gold and silver threads on rich velvet or linen grounds. Such English embroidery was in great demand across Europe, particularly from the late 12th to mid-14th centuries and was a luxury product often used for diplomatic gifts.

A needlework sampler is a piece of embroidery or cross-stitching produced as a 'specimen of achievement', demonstration or a test of skill in needlework. It often includes the alphabet, figures, motifs, decorative borders and sometimes the name of the person who embroidered it and the date. The word sampler is derived from the Latin exemplum, which means 'example'.

Embroidery hoops and frames are tools used to keep fabric taut while working embroidery or other forms of needlework.
