Up North - that's the type ornament I meant. The scrap of fabric was laid on the styrofoam shape and the edges pushed in to the foam.
I have made a 'pinetree' using 1" squares of a variety of green fabrics, and then pushing the center of the square into the foam. It was a cone shape and it was entirely covered except for the base. We then put the base into a small terracotta flower pot.
I know this doesn't have anything to do with the original question but I thought someone be interested!
