Crafty Homemade Air Freshener Instructable

This air freshener instructable is awesome and since it uses dryer sheets for the air freshening job I imagine it wouldn't bother my nose as much as normal air fresheners do (there are a lot of dryer sheets out there with a very subtle scent).
I think these would make a great gift for someone assuming you assure them that you don't think they stink before presenting the gift.
