Heavy Embroidery Needles, the name relates to their size, not their usage; they are not heavy to use. They are the largest in the Embroidery needle family, most typically employed when working with twisted yarns, for example, doing yarn embroidery on a chucky heavy-knit jumper/sweater.
The pack contains 2 needles, both are Size 14. One has a sharp point and one has a rounded blunt point. Selection of the most suitable one will depend on the fabric weave openness
