Brillant are ye! I too used laundry detergent containers. First my local(in my bldg) pharmacy gave me FREE red sharp holders and took them back free! Then they started charging. BTW I used to work in recycling for city of Seattle (not sure why I feel need to preface this...my great expertise?) Love "repurposed." I shall steal that for my upcoming recycling lecture at my retirement home.(oops, we, and by "we" I mean the owners, prefer "retirement community.")
Brilliant too!! (geez)
Fantastic idea, too bad I don't have any of the official "containers," I thought they might be an urban myth.
