Blocking is an essential but often overlooked step in knitting. Once a project is off the needles, blocking is like waving a magic wand over your knitting to bring it from good to great – yarn blooms to incredible softness, stitches smooth out to a uniform look, and lace stitches transform to a delicate beauty. Blocking wires are easily used to make the straight lines in your knitting straight. Blocking puts the finishing touch on your hand knits, which is made a much simpler and faster experience when blocking wires (blocking pins) are used. Blocking your finished project infinitely improves its appearance. These SS304 Stainless Steel T pins are rust resistant and 1.75" long.
