A novel and original idea to block knitting projects….guaranteed to make knitting lives easier!! The ease of handling the blockers substantially speeds up blocking on all types of projects. The design helps maintain even tension across the width of the blocking pins. Ideal working on blocking straight edges like sweaters, shawls and scarves. Anchor holes in each blocker allows the user to attach string along large sections which can be pulled and pinned to maintain consistent tension. Made using tough plastic with embedded sharp, sturdy & rust resistant stainless steel pins. Two different sizes to manage different shapes when blocking. Designed by knitters for knitters. 12 Blockers with 8 Pins and 8 Blockers with 4 Pins.
