I am making pot holders for some of the women in my family for Christmas and I thought I would share them with you.
1. Always be sure to use 2 layers (or more) of Insul-Bright no matter what the pattern calls for.
2. Always use a 100% cotton batting like Warm and Natural.
3. Always use 100% cotton fabric.
My grandmother bought some "puffy" pot holders at a craft show because she thought they were "nice and thick". When she tried to use them, they were worthless! The lady used a high loft poly blend batting with no Insul-Bright. The might have looked thick, but they did not protect her hands against the hot pan at all! "Puffy" and "thick" doesn't mean they'll hold up to the heat.
Here are some different links for making/using pot holders:
