Sew~In Warm Fleece is manufactured with the BEST 100% Polyester Fibers available in the world (because they’re made in the USA!) and with The Warm Company's state of the art manufacturing - we've just set the standard for fleece a lot higher. First you’ll notice the softness, then the nice hand, the perfect loft and finally the care we put into all Warm products. The soft, polyester fibers enhance sewing, quilting and crafting projects by adding gentle shape, dimension and texture. Warm Fleece is ideal for use in projects calling for interlining & padding like placemats, table runners, wallhangings, baby bibs, picture frames, holiday decorations, totes, purses, jackets and vests. Warm Fleece will not shrink or lose its shape. No prewash required. Machine washable, dryer safe and dry cleanable - Warm Fleece works well with all kinds of fabrics.
