(I don't mean the bin! :o)
I rarely venture onto A&C board as I am crap with all crafty things really, would love to be better! But DD had a shaker maker for her birthday and we had used up the plaster stuff, so DH melted a load of old crayons and poured them in. Giant crayons! :) He also did one with layers of different colours.
Just thought I'd post it in case anyone else wanted to try.
