8” Small Tailor's Clapper is perfect for pressing seams for quilting or sewing. This clapper is made from unfinished oak, which helps absorb moisture from fabric to leave flat, crisp seams. Both sides have a groove for easy handling. Press your seam with your steam iron, then apply the clapper and firm pressure to set the seam. Use them on quilt blocks or garments for seams, creases and pleats.
