An important step in knitting is blocking, a technique of steaming or wetting your fabric pieces to adjust and set their shapes. Blocking mats are incredibly useful tools that can improve the precision of this process. Resembling the interlocking pieces of a child’s play mat, these lightweight boards can be arranged to accommodate pieces of many sizes. They’re designed to handle being pricked with pins and often feature gridlines to assist with alignment. Improve the shape of your knitted works with the top blocking mats we’ve found.
