T-pins are another one of those essential tools for knitters and textile artists as a whole. They're great for blocking your knits or wovens, and the T shape holds everything nice and secure.
This tin from Cocoknits comes with 40 stainless steel pins. Stainless steel is key - you don't want rust stains on your freshly made work! Plus, it means these will stick to your Maker's Keep!
