Beading needles are great for attaching beads. They are very different from sewing and craft needles. They have narrower eyes and are overall thinner. This enables them to pass smoothly through tiny bead holes. The bigger the number, the narrower the needle. Size 10, 11, and 12 are the most popular for bead weaving, whilst Size 13 is used for extra-small beads. The pack comes with 6 different sizes needles varying from 10 to 13.
