Designed by knitters, Knit Blockers are a novel and original idea to block knitting projects that's guaranteed to make knitting lives easier!! The ease of handling the blockers substantially speeds up blocking on all types of projects and the design helps maintain even tension across the width of the blocking pins. It's ideal working on blocking straight edges like sweaters, shawls and scarves, and the anchor holes in each blocker allows the user to attach string along large sections which can be pulled and pinned to maintain consistent tension. It's made using tough plastic with embedded sharp, sturdy and rust resistant stainless steel pins, and comes in two different sizes to manage different shapes when blocking.
