A slat or vane (30) for use in a covering for an architectural opening is suitable for use in either a horizontal or vertical orientation and in a horizontal orientation will not sag or droop, and in a vertical orientation will rotate uniformly along its length when rotated from end thereof. The slat (30) is formed in a tubular configuration and has a base material of glass fibers bonded together in a thermoformable resin so as to maintain the arcuate curvature desired for the tubular slat or vane (30). The slat ( 30) can be repeatedly deformed and will always return to its original configuration.

What is claimed: 1. A slat for a covering for an architectural opening comprising in combination: an elongated tubular body formed from a material including glass fibers in a thermosetting resin which has been heated above its setting temperature whereby said body is flexible, resilient and will return to its original configuration after repeated deformations. 2. The slat of claim 1 wherein said material is a laminate including a first layer of glass fibers in said thermosetting resin and a second layer of a different material. 3. The slat of claim 2 wherein said first and second layers are bonded together. 4. The slat of claim 3 wherein said bonding is with a thermosetting adhesive. 5. The slat of claim 2 wherein said second layer is a fabric material. 6. The slat of claim 5 wherein said fabric material is woven. 7. The slat of claim 5 wherein said fabric material is non-woven. 8. The slat of claim 5, wherein said fabric material is a foil. 9. The slat of claim 1 wherein said slat is formed from a single strip of material having opposed edges that is folded along an approximate longitudinal centerline and the opposed edges are secured together. 10. The slat of claim 8 wherein said opposed edges are disposed exteriorly of the tube defined by said body. 11. The slat of claim 9 wherein said opposed edges are disposed interiorly of the tube defined by said body. 12. The method of forming a tubular slat for a covering for an architectural opening comprising the steps of: providing an elongated strip of material having opposed longitudinal edges, said strip including glass fibers in a thermosetting resin which has been heated above its setting temperature, folding said strip along an approximate longitudinal line so that said edges are in adjacent relationship, and securing said edges together. 13. The method of claim 12 further including the step of forming said strip with an arcuate transverse configuration before said folding step. 14. The method of claim 13 wherein said edges are secured together exteriorly of the tube defined by said slot. 15. The method of claim 13 wherein said edges are secured together interiorly of the tube defined by said slat. 16. The method of claim 13 wherein said edges are secured together with a thermosetting adhesive. 17. The slat of claim 1, wherein the tubular body comprises a upper side and a lower side, the lower side having downwardly convex outer surface, and the upper side having an upwardly convex outer surface, the upper side intersecting with the lower side along two opposing edges. 18. The slat of claim 17, wherein the upper and lower sides formed from a single strip of material having two ends, the two ends overlapping to form the tubular body. 19. The slat of claim 18, wherein one of the opposing edges is formed by a fold in the single strip of material. 20. The slat of claim 19, wherein the other of the opposing edges is formed by an overlap of the two ends. 21. A method comprising: providing a thin elongated strip having opposite longitudinal edges, the elongated strip comprising a fibrous mat and a thermosetting resin disposed in the fibrous mat; forming the elongated strip to have a resilient arcuate transverse configuration by cross linking said thermosetting resin contained with in the fibrous mat; folding the elongated strip along at least one longitudinal line; and joining the opposing longitudinal edges together to form a tubular body having a upwardly convex top surface and an opposing downwardly convex bottom surface; and heating the strip above its setting temperature. 22. The method of claim 21, wherein the fibrous mat comprises fiberglass. 23. The method of claim 22, wherein the fiberglass is non-woven. 24. The method of claim 21, wherein said folding the elongated strip along at least one longitudinal line further comprises folding the longitudinal strip along first and second longitudinal lines. 25. The method of claim 24, wherein the first longitudinal line is proximate the transverse enter of the strip between the opposing longitudinal edges, and the second longitudinal line is proximate one of the longitudinal opposing edges. 26. The method of claim 24, wherein said joining the opposing longitudinal edges together to form a tubular body further comprises: overlapping a first portion of the elongated strip located between the first longitudinal edges, and a second portion of the elongated strip located between the second longitudinal line and the other of the opposing longitudinal edges; and bonding the first portion to the second portion with an adhesive. 27. The method of claim 26, wherein the adhesive is a thermoplastic copolyester. 28. The method of claim 21 further comprising applying a layer of material to a surface of the elongated strip prior to said forming the elongated strip. 29. The method of claim 28, wherein the layer of material comprises a woven fabric. 30. The method of claim 28, wherein the layer of material comprises a non-woven fabric. 31. A slat for an architectural covering comprising: an upwardly convex first elongated side having left and right longitudinal edges; and a downwardly convex second elongated side having left and right longitudinal edges, the left and right longitudinal edges of the first side being coextensive with the left and right longitudinal edges of the second side; wherein the first and second elongated sides are both comprised of a thin fibrous mat having a thermosetting resin disposed within the fibrous mat with the resin having been heated above its setting temperature such that the fibrous mat is resilient and flexible having configuration memory such that it will return to its original configuration after being deformed. 32. The slat of claim 31, wherein the first and second elongated sides are comprised of a single continuous piece of the fibrous mat, the single piece of fibrous mat having first and second ends and being folded along either the left or right edge of the first or second elongated sides. 33. The slat of claim 31, wherein the fibrous mat comprises fiberglass. 34. The slat of claim 31, wherein the fibrous mat is non-woven. 35. The slat of claim 31, wherein the resin is a thermoset. 36. The slat of claim 31, wherein the first longitudinally extending side further comprise a second layer of material, the second lay of material laminated to a surface of the fibrous mat. 37. The slat of claim 36, wherein the second layer of material comprises a fabric. 38. The slat of claim 37, wherein the fabric is woven. 39. The slat of claim 37, wherein the fabric is non-woven. 40. The slat of claim 36, wherein the fabric is laminated to the surface of the fibrous mat by an adhesive resin. 41. The slat of claim 40, wherein the adhesive resin is a thermoset. 42. The slat of claim 32, wherein the fold at the left or right edge is proximate a centerline between the first and second ends. 43. The slat of claim 32, wherein the first and second ends are joined together in an overlapping relationship. 44. The slat of claim 42, wherein the first and second ends are joined together in an overlapping relationship proximate the left or right edge opposite the fold. 45. The slat of claim 31, wherein the resin content of the fibrous mat is approximately 21% to 24% by weight. 46. The slat of claim 31, wherein the slat is translucent. 47. The slat of claim 1, wherein the thermosetting resin content of the material is approximately 21% to 24% by weight. 48. The slat of claim 1, wherein the slat is translucent. 49. The slat of claim 1, wherein the slat is disposed horizontally and does not noticeably droop or sag. 50. The slat of claim 31, wherein the slat is disposed horizontally and does not noticeably droop or sag.
