Project Ideas for Insul-Bright Insulated Batting

Project Ideas for Insul-Bright Insulated Batting
Quilted potholders and insulated casserole carriers are excellent projects for Insul-Bright insulated batting. With its combination of insulation and heat conduction, Insul-Bright helps protect your hands from heat while keeping dishes warm. You can also use Insul-Bright for other kitchen items like oven mitts, trivets, and microwave bowl holders to enhance heat resistance and safety.

Quilted Potholders

Creating quilted potholders with Insul-Bright insulation is a great way to add durability and insulation to your potholders. Here’s a step-by-step guide on how to make a quilted potholder using Insul-Bright:

  1. Choose your materials: You’ll need a fabric for the top of your potholder, Insul-Bright for insulation, and a layer of cotton batting for padding. You can also use a backing fabric for the back of your potholder.
  2. Prepare the layers: Layer the materials in the following order: the backing fabric (wrong side up), the Insul-Bright (there is no right or wrong side to this fabric), the cotton batting, and the top fabric (right side up).
  3. Pin the layers: Pin the layers together to secure them for quilting.
  4. Quilt the potholder: Use a home sewing machine with a walking foot to quilt the potholder. Straight line quilting and stitching in the ditch are both great options for this project.
  5. Trim the potholder: After quilting, trim the potholder so the edges are even, cutting away excess batting and backing layers.
  6. Make the binding: To make the binding, start at one end of your fabric strip and fold the strip in half lengthwise (wrong sides together), pressing until you have reached the end of the strip.
  7. Bind the potholder: Bind the potholder using prepared binding or purchased ready-made binding. Bind the potholder just as you’d bind a quilt.

Remember to use a walking foot or free motion foot for quilting, as the layers can be quite thick. You may also want to baste around all edges 1/8 from the edge to keep the layers together while binding.

Insul-Bright Vs. Insul-Fleece

Insul-Bright Vs. Insul-Fleece
While both Insul-Bright and Insul-Fleece are insulating materials used in quilting and pot holder projects, there are distinct differences between the two. Insul-Bright features silver threads woven into the batting, while Insul-Fleece has a shiny, silver side that must face outwards to provide effective heat insulation.


Insul-Bright and Insul-Fleece are two distinct products designed for different purposes.

Insul-Bright is a metallic poly sheet with polyester batting, providing extra insulation and preventing heat damage. It is commonly used in pot holders, casserole carriers, and other insulated projects.

Insul-Fleece is a crinkly-sounding, silver-coated fleece used in pot holders, offering heat retention and a shiny appearance.

Both materials have their unique benefits, but they serve different needs in the context of insulated products.


Insul-Bright and Insul-Fleece are two different insulation materials with distinct features and uses. Insul-Bright is a needle-punched, insulated material made of polyester fibers and a reflective metalized polyester film. It reflects radiant energy, hot or cold, back to its source, making it ideal for heat-safe projects like pot holders, oven mitts, and casserole covers. Insul-Bright is washable, breathable, and resistant to conduction. It isn’t recommended for microwave use and can be used in clothing, although it may be noisy due to the crinkling film.

On the other hand, Insul-Fleece is also made of polyester fibers but doesn’t have the reflective metalized polyester film. It’s often compared to Insul-Bright but is considered less effective. Insul-Fleece isn’t as stiff as Insul-Bright, which is known for being quite stiff, and it may not provide the same level of insulation.

In terms of heat retention, Insul-Bright is designed to reflect heat back to its source, making it a more effective insulator. However, it’s important to note that using Insul-Bright for projects exposed to prolonged high temperatures, such as microwave use, isn’t recommended.

When it comes to durability and ease of use, both materials are suitable for sewing and crafting projects. Insul-Bright is known for its crinkly sound, which can be attractive to babies and animals, while Insul-Fleece doesn’t have this characteristic.
