hello to everyone.
i have a different idea.
how about make a reversible sign out of paper and laminate it to protect it (you can buy laminate sheets cheap at walmart).
i would draw a circle and put a happy smiley face on one side
and a frown smiley face on the other (happy=clean,sad=dirty)
you could use yellow paper,or marker,color pencils,paint etc.
you could also make it out of stitching canvas or felt or wood.
then put a hole in the top and add a ribbon to hang it on the handle of the dishwasher or use a suction cup to adhere it to the dishwasher front.
it seems most dishwashers have plastic fronts now-a magnet might not work.
sincerely-sheila ann anderson
