Works perfectly with knitting mats: Each knitting blocker pin features a 2cm needle length, specially designed to insert smoothly and securely into standard foam blocking mats. The sturdy multi-pin design grips multiple stitches at once, helping keep crochet, knitting and lace pieces flat and aligned while they dry into the precise shape you want. Two knit blockers comb size options: This upgraded knit blocking includes 8 pcs short 4- combs and 12 pcs long 8- combs, allowing you to choose the ideal length for edges, corners and straight lines. Easily secure your handiwork on blocking mats so projects stay taut, evenly shaped and firmly in place for professional-looking results. Save time on blocking projects: Compared with traditional single T-pins that require placing dozens of pins one by one, these knit blocking combs let you anchor long edges and curves in seconds. You can quickly arrange your crochet squares, shawls, sweaters or lacework, greatly reducing blocking time while improving accuracy and consistency on every project. Safety attention and wide application: The blocking pins feature metal points, so please keep them away from children and pets, and store separately from delicate fabrics or items to avoid accidental damage. Ideal for crochet, knitting, sewing, lace needlework and other fiber arts, this kit is a practical tool for beginners and experienced crafters.
