Made of Oak wood. Used with steam from your iron, press the area with the clapper and hold for just a few seconds, it will leave a nice crisp seam.
Small Size: Width Measurements are 1-3/4in tapered down to 1-1/4in, Length is 7-3/4in
Large Size: 11-1/2in long, 3in wide tapered down to 2-1/2in and is 1-1/2in thick.
After following a few quilter’s instagrams and blogs about the clapper, I had to give it a try. I am not sorry I purchased this. It really does help
flatten your seams and keep them nice and crisp.
