There is disclosed a thermal insulating material especially suitable for a bed quilt in which there is a filling in the form of a coherent sheet or strip enclosed between two layers of sheet material, lines of stitching are formed between the layers of sheet material and pass through the filling, the stiches being such that whilst it prevents any substantial movement of the filling relative to the material in use, the layers of material along the lines of stitching will be held apart by the pressure of the filling. The layers of sheet material may be spaced strips of material extending along each side of the filling, the stitching passing through the strips, an outer cover which may be secured to the strips may be provided. |
