"Because the Weavercraft cannot possibly supply every Hold, each makes its own hand looms, crochet hooks, spindles, and shuttles." (DLG, p134)
Needles with large eyes and blunt ends are tapestry needles. They are used for whipped and lace stitches, canvas embroidery, drawn fabric and drawn threadwork. Sharps are needles of medium length, and are used for sewing thread or a single strand of floss. Crewel needles are long and sharp, with a long eye, and are used for embroidering stranded floss. Beading needles are extremely fine.
Crochet and knitting needles are completely different from sewing or embroidery needles. They have no eyes, and are substantially larger, although they come in many different sizes depending on what they will be used for. Knitting needles are used in pairs. Crochet needles (or hooks) have a hook at the top which is used to drag the yarn through the crochet loops.
