Product Overview
Bosal Poly-Therm Fleece is a specialized heat-reflective material designed for a wide range of home crafting projects. Its unique construction allows it to reflect heat, making it ideal for both insulating and heat-resistant applications.
The fleece features a white side suitable for machine or hand quilting, providing dimensional effects, and a silver lining on the reverse side that actively reflects heat back to its source. This dual functionality makes it versatile for various uses, from keeping items warm to keeping them cool.

Setup and Preparation
Bosal Poly-Therm Fleece comes as a single piece, measuring approximately 36 inches by 62 inches (91.44 cm x 157.48 cm). Before use, unroll the fleece and lay it flat to remove any creases. It can be easily cut to the desired size and shape using standard fabric scissors or rotary cutters.
The fleece is designed for machine or hand quilting. Ensure your sewing machine is set to an appropriate stitch length for fleece materials. When incorporating into projects, consider the orientation of the white (quilting) side and the silver (heat-reflective) side based on your project's thermal requirements.
Important Usage Notes and Safety
When using Poly-Therm Fleece for projects that will come into direct contact with extreme heat, such as pot holders or oven mitts, it is crucial to add an additional layer of protection. A layer of 100% cotton batting is strongly recommended as a shield between the outer fabric and the Poly-Therm Fleece. This precaution is necessary because extreme heat can cause the polyester fleece and polyethylene film to melt.
Always test a small scrap piece with your intended heat source if you are unsure about its application in high-temperature environments.
Maintenance and Care
Bosal Poly-Therm Fleece is designed for easy care. It can be machine washed and dried. For best results and to maintain the integrity of the material, follow these general guidelines:
- Washing: Use a gentle cycle with cold or warm water. Avoid harsh detergents or bleach.
- Drying: Tumble dry on a low heat setting or air dry. High heat can potentially damage the reflective film.
- Ironing: Avoid direct ironing on the silver reflective side, as high heat can cause melting. If ironing is necessary, use a low setting and iron from the fabric side, or use a pressing cloth.
