Sadly, a template was not provided. However, the construction process is easy to adapt. You can use a hexie template you already have, Google for a hexie to print of the size you want, or follow the instructions and draw out your own (convert centimeters to inches here). That also means you can make the hot pad as large or small as you want.
The instructions specify overlapping seam allowances before fusing and stitching the hexies down to a foundation fabric. You’ll achieve more consistent hexie shapes if you butt them up next to each other instead.
Once you have your template and have made one, you can quickly make several more. The hot pads are great gifts while also being a good use of scraps.
