Latch hook is a craft technique used to create rugs, wall hangings, and other textile art. It involves using a special tool called a latch hook to pull yarn through a canvas grid, forming loops that create a design. The canvas is typically pre-printed with a pattern, making it easier for crafters to follow along. This technique is popular among both beginners and experienced crafters due to its simplicity and versatility. Latch hook projects can range from small items like pillows to larger pieces like area rugs, allowing for creative expression in various forms.
