Abstract: A window shade with extendable edges or inserts is described. A set of cellular inserts 2 are slidably displaced within the cells 12 of a honeycomb shade 10. The inserts 2 have a cross-sectional shape similar to the cross-sectional shape of the honeycomb shade cells 12. The inserts 2 extend within the cells longitudinally a distance 22. At a distal edge 6 of the honeycomb shade 12 the inserts 2 are connected together. A notch 5 is attached to the inserts along near distal edge 6. The notch 5 allows a user to pull the inserts 2 in a uniform manner out from the cells 12 of the honeycomb shade 10 a preferred extended distance 66. The user is thereby able to extend the sunblocking ability of the honeycomb shade.
