Large arrangement in a big basket
I want to make an artificial flower arrangement in a rather large basket. I always use florist foam in smaller baskets and since my arrangements have been small, I push the foam to the bottom and proceed.
My question is, since the basket is so large, are there any suggestions for filling the bottom on the basket with something else and then adding the regular foam on top (which will be enough to hold flowers in place). I have thought of plastic bags or styrofoam peanuts. Has anyone done anything else?
