Jacksons Woodworks has just made ironing that block easier. The Quilter’s Clapper has been designed to flatten those larger areas. It is used to press seams without burning. It holds the steam in after ironing, and the extra time with the steamed heat acts to flatten the seams more than is possible with the iron alone.
Used with steam from your iron, press the area with the Quilter’s Clapper and hold for just a few seconds, it will leave a nice, flattened seam.
The top is rounded over and smooth with a wooden knob for easy pick up. The clapper is unfinished to absorb the steam better.
