Pinnable Quilt Block Markers allow you to keep your quilt pieces and blocks organized. Use your own pins with a Block Marker to pin a letter or number to your pieces. Use them to keep track of your blocks for your Block of the Month projects. Each letter and number was custom designed to make them easy to read at a glance. Choose from a variety of bright colors to contrast with your fabrics. Each set includes the full alphabet (A-Z) and numbers (0-9) for a total of 36 pieces. Use two colors to easily separate the pieces of a block that uses mirrored pieces.
