DIY Round Polka Dot Pot Holder with Heat Shield

DIY heat shield trivet

My Mom and I have been collecting vintage Pyrex together for years, but we never saw eye to eye on the clear Pyrex flameware: clear glass pots, double boilers, coffee makers, tea kettles, etc.  I thought they were boring, but my Mom discovered that they work really well with glass top stoves because their bottoms are really flat.  When my Mom got her glass top stove, I was moving out so she gave me some of her wibbly wobbly pots and pans and started collecting flameware.  Fast forward three ovens, and many years later, and now I have a glass top stove too!  I curse her hand-me-down pots every time I use one - and now I see the appeal of Pyrex flameware.

So far, the only flameware I actually have is the tea pot/kettle, which is genius!

Boil the water and steep the tea in the same beautiful vessel - perfect for a small kitchen like mine because I no longer need a separate tea pot.  Plus the glass pot looks so pretty sitting on the stove.

The only downside is that the glass lid gets really hot, so I wanted a little aqua pot holder to use with my tea pot.  My Mom and I whipped one up, using leftover fabric from the polka dot laundry room curtains.

Isn't it adorable?  I wanted a round shape to complement the polka dot fabric, and a small loop so I could hang it up beside the stove.

It was a breeze to make and required only a few supplies:

  • Cotton fabric (this one is kind of similar)
  • Thread
  • Sewing machine
  • Ribbon or twill tape for loop
  • Heat shield fabric (also called heat reflective fabric or poly-therm fleece)
  • Scissors
  • Paper for circle templace
  • Round object to trace (like a plate)


First we used a round plate - slightly larger than the size I wanted the finished pot holder to be - and traced it onto graph paper to use as a template.

We pinned our template onto the fabric and cut out three pieces: two circles from the polka dot fabric, and one circle from the heat shield fabric.

With the circles cut, we cut out a piece of twill tape for the loop.

Then we pinned the three circles together.  Because the fabric is reversible - and I wanted one side cream on aqua and the other side aqua on cream - we pinned them together so the "right" sides were facing each other, and the heat shield fabric was on the bottom.  Here's a peek at the order:

We tucked the loop between the two fabric circles, facing away from the edge.  We sewed the edges with the machine, leaving an opening to turn everything right side out.

To make the curved shape easier to flip, we cut little notches around the circumference.

We turned it right side out and then sewed shut the small opening.

And, voila, a perfectly-sized pot holder to solve my oddly specific kitchen dilemma:

(I've been itching to make one of these since we made those adorable, child-sized pot holders and itty bitty tea towels for the play kitchen we made.)

How to make a pot holder with heat shield material


  1. I think I need a teapot like that for our glass top stove. I didn't realize you can use those on top of the stove. I'll definitely be keeping my eye out for one (or more).

    1. Yes - these pots are amazing. They can boil the water, steep the tea and - if you don't have a microwave, like me - warm up any leftover tea for later. My only advice is to be very careful if you store it on your stove. I accidentally turned on the element under it while I was cooking and because it was empty it nearly exploded! Luckily my Mom had a spare. I hope you find one!

    1. Thanks!! I'm kind of smitten with that fabric :)

  3. I grew up with this teapot and still use it every day. Had no idea that it was a kettle too!! Suddenly it makes total sense, it's Pyrex! Thanks for helping me clear my own clutter. Does anyone need a kettle?

    1. Happy to help! I only knew because one of my Pyrex books features a few vintage ads that explained the two-in-one function.
