Different projects need different sized needles. Schmetz realized this and that is why they specialize in creating the perfect needle for all sewing needs.
Schmetz stretch needles are for highly elastic synthetic knitwear, like lightweight or silk jerseys. The medium ball point and specially designed eye and scarf help reduce skipped stitches and make this needle perfect for both knits and elastic or stretch fabrics.
Each package contains 5 specialty needles.
