Numbered Pins is the perfect solution for organizing quilt blocks, rows and columns when order is important to the design of the quilt. Use these high quality, stainless steel, flat head pins as a simple tool to keep your project organized without disturbing your layout. Simply pin a Numbered Pin in the upper left hand corner of a block, row or column to keep track of specific pieces as you rotate or shift your fabrics. A quantity of pins for each number (1-20) is provided for easy organization for any sized project. Numbered Pins are a great alternative to masking tape, especially when residue can damage the fabric, and they replace those annoying, one-time-use sticky notes. Need to add more numbers, letters or color codes? Simply customize the back of each pinhead with a permanent marker. Our reusable product will not damage fabric and remains stationary while assembling your quilt.
