Knitter's Pride Knit Blockers - sturdy, rust resistant stainless steel pins embedded in tough plastic handles in two sizes to accommodate different project shapes make blocking easier, faster and fun. The ease of handling the blockers substantially speeds up blocking and the clever design helps maintain even tension across the width of the blocking pins. Anchor holes in each blocker can optionally be used with string or blocking wires to maintain consistent tension along large sections. Each set of 20 knit blockers comes in a plastic storage case and includes 12 knit blockers with 8 pins and 8 knit blockers with 4 pins. An innovative solution that will leave you wondering why no one has done this before!
