Consider this as a different kind of Hidden Tech (tech category: energy conservation; hidden by usually being sewn between layers of fabric)... *Thinsulate insulation *(by 3M), 45" wide by about 40 yards long. Free to a non-profit or "make offer" to anybody. 3M describes it as being useful as "interlining for winter jackets, blankets, and other winter specialty clothes." It's white, maybe 1/4" thick, spec'd at 5.9 oz. per yard. We used part of a 70-yard roll to make insulating Roman shades; we don't need the rest. This roll is the C200 version of Thinsulate. For comparison, the C150 version, at 60" wide and 4.6 oz./yard, is available online at about $10/yard! Manufacturer's directions for that product: "Sew this as an interlining. Use your lining pattern pieces to cut the Thinsulate, then stitch the Thinsulate to the lining before sewing to the outer fabric. it provides about 1-1/2 times the warmth of down and about twice the warmth of other high-loft insulation materials."
