T-pins are an essential part of the COCOKNITS KNITTER'S BLOCK KIT. If you aren’t sure if your T-pins are stainless, soak them overnight in a shallow dish of water. If they rust, do not use them! Cocoknits T-pins are stainless steel – which means they won’t rust when they get wet during blocking – very important after you’ve spent many hours and dollars on a project!
