I love the fuzzy dice idea - and think it would be great for adults to use too for a costume party - maybe the dice would show a roll to equal - pairs!
If anyone is still struggling and only 3 days away - I have to toot my own horn. My 5th grade daughter and her best friend had planned another costume but it would have been covered by their coats and we are told to expect snow (yuk!) so quick thinking - - -
Took 2 moving boxes, taped closed and spray painted white, then covered with batting (used for quilting and making pillows - happens to be 50% off at JoAnn Fabrics this week) then applied black felt dots. Voila - the two girls will now be fuzzy dice and when cut outs for head & arms fits well over winter coats.
As a girl scout leader whose troop has been in 2 halloween parades - we used the same box concept wrapped in holiday paper and voila - they were "gifts" in the parades.
