The sleeve is constructed to include one or more channels within the interior of the sleeve for receiving prongs of a duster handle. The fibrous bundles are attached to the surface of the sleeve or through the sleeve. The channels within the sleeve may include one or more narrowing areas to facilitate retention of the prongs within the sleeve. ## Claims ### Claim 1 A duster comprising: a sleeve constructed of at least two sheets of overlapping material and including at least one top sheet and at least one bottom sheet and defining a space there between; a top fibrous bundle attached to an exterior surface of the top sheet by at least a first non-linear joint that extends through the top fibrous bundle and adheres to the exterior surface of the top sheet of the sleeve; a bottom fibrous bundle attached to an exterior surface of the bottom sheet by at least a second non-linear joint that extends through the bottom fibrous bundle and adheres to the exterior surface of the bottom sheet of the sleeve; a center joint joining the at least one top sheet and the at least one bottom sheet of the sleeve together, the center joint extending longitudinally down and substantially centered on the sleeve; and at least two side joints further joining the at least one top sheet and the at least one bottom sheet of the sleeve together, the at least two side joints extending longitudinally down and offset from the center of the sleeve to create at least two channels between the at least one top sheet and the at least one bottom sheet of the sleeve, and wherein the two side joints flare away from the center joint to widen the channels proximate to an opening of the channels. ### Claim 2 (depends on 1) The duster of claim 1, further comprising a means for further attaching the top fibrous bundle to the exterior surface of the top sheet and a means for further attaching the bottom fibrous bundle to the exterior surface of the bottom sheet to cause a separation of various fibers within the fibrous bundles. ### Claim 3 (depends on 1) The duster of claim 1, wherein the means for further attaching the top fibrous bundle and the bottom fibrous bundle includes one or more tacking joints. ### Claim 4 (depends on 1) The duster of claim 1, wherein the means for further attaching the top fibrous bundle and the bottom fibrous bundle includes an adhesive. ### Claim 5 (depends on 1) The duster of claim 1, wherein the at least two sheets comprise at least two separate sheets. ### Claim 6 (depends on 1) The duster of claim 1, wherein the at least two sheets comprise at least one single sheet that is folded over itself. ### Claim 7 (depends on 1) The duster of claim 1, wherein the at least two sheets define a flaps at an end of the sleeve proximate to the opening of the channels, wherein the flaps extend beyond the first and second non-lineal joint. ### Claim 8 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the at least one top and at least one bottom sheets. ### Claim 9 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the top and bottom fibrous bundles. ### Claim 10 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the at least one top and at least one bottom sheets and the top and bottom fibrous bundles. ### Claim 11 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the at least one top and at least one bottom sheets. ### Claim 12 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the top and bottom fibrous bundles. ### Claim 13 (depends on 7) The duster of claim 7, wherein the flaps are a different color from the at least one top and at least one bottom sheets and the top and bottom fibrous bundles. ### Claim 14 A duster comprising: a sleeve constructed of at least two sheets of overlapping material and including at least one top sheet and at least one bottom sheet and defining a space there between; a top fibrous bundle attached to an exterior surface of the top sheet by at least a first joint that extends through the top fibrous bundle and adheres to the exterior surface of the top sheet of the sleeve; a bottom fibrous bundle attached to an exterior surface of the bottom sheet by at least a second joint that extends through the bottom fibrous bundle and adheres to the exterior surface of the bottom sheet of the sleeve; a center joint joining the at least one top sheet and the at least one bottom sheet of the sleeve together, the center joint extending longitudinally down and substantially centered on the sleeve; and at least two side joints further joining the at least one top sheet and the at least one bottom sheet of the sleeve together, the at least two side joints extending longitudinally down and offset from the center of the sleeve to create at least two channels between the at least one top sheet and the at least one bottom sheet of the sleeve, and wherein the two side joints flare away from the center joint to widen the channels proximate to an opening of the channels. ### Claim 15 (depends on 1) The duster of claim 1, further comprising a means for further attaching the top fibrous bundle to the exterior surface of the top sheet and a means for further attaching the bottom fibrous bundle to the exterior surface of the bottom sheet to cause a separation of various fibers within the fibrous bundles. ### Claim 16 (depends on 1) The duster of claim 1, wherein the means for further attaching the top fibrous bundle and the bottom fibrous bundle includes one or more tacking joints. ### Claim 17 (depends on 1) The duster of claim 1, wherein the means for further attaching the top fibrous bundle and the bottom fibrous bundle includes an adhesive. ### Claim 18 (depends on 1) The duster of claim 1, wherein the at least two sheets comprise at least two separate sheets. ### Claim 19 (depends on 1) The duster of claim 1, wherein the at least two sheets comprise at least one single sheet that is folded over itself. ### Claim 20 (depends on 1) The duster of claim 1, wherein the at least two sheets define a flaps at an end of the sleeve proximate to the opening of the channels, wherein the flaps extend beyond the first and second non-lineal joint.
