Lay out your washed garment on this surface to dry. Mittens and gloves will fit on one square. If the knitting requires drying under tension, such as lace, use these mats in conjunction with blocking wires and T-pins.
As I say in many of my classes, “Blocking is magic!” It improves your final product by helping the stitches to “settle in”, and allows the yarn to relax and bloom. The fabric will appear more smooth and look finished.
