Picture of How to Make a Tailor's Clapper

A tailor's clapper is a tool that helps you get amazingly crisp, flat pressed seams and creases.  To use it, you first press your seam with a hot iron and lots of steam.  Immediately after lifting the iron, you place the clapper over the seam and hold it down until the fabric cools.  This traps the heat and steam in the fabric, making the seam as flat as possible.  Tailor's clappers are made out of hardwood.  I had a piece of maple hanging around, so I made a clapper at TechShop Menlo Park .  It's a very simple thing to make, so here's what I did.

My piece of maple was about 1 1/4" by 1 1/4" by 12".  Clappers are generally about 2" to 3" wide, but I decided to use my skinny piece for now and make a larger one later.  I drew a half circle at both ends to mark where I was going to round it off.

Step 1: Cut Rounded Edge With Band Saw

I used a band saw to cut the rounded edge.  First I cut a series of relief cuts down to the curved line (see photo).  The relief cuts make it much easier to cut a curved shape in the wood.  I then cut off the excess, leaving me with a nice curve on either end.  It's still pretty rough though, so on to the next step!

Thank you genius! I came here on a whim just hoping to find a clapper. What Unbelievable luck! I'd rather make whatever I can and this seems so doable. I'll report back once I'm done.

That's awesome, simple, easy & quick. You could probably use that as a seam roll as well. Check out Kenneth King's article on to see what I am talking about "A New Improved Seam Roll".

Now if I can just get my hubby to make me one ;)

I think it's a simple effective instructable. It may not be something I'll ever use, but your instructions were clear and concise. You could use a band saw, a jig saw, or grind away with a belt sander, it doesn't matter as long as it's a snag free rounded corner. Your way is just fine. Thanks!
I like it, but its too diy. Next time you should use a 3D printer. lol

Nice. Next time, skip the band saw, and go ahead and create your rounded corners with the belt sander. It will work just fine.
