Fall basket and set of 5 fall cards

I decorated a basket for the fall and in it will be these 5 cards pictured and envelopes. I am doing baskets to sell at our school's silent auction on November 5. The next one I will do is a Christmas basket with some Christmas cards in it and a small champagne glass with a candle in it. I tried to use saran wrap to cover the baskets and their contents but that didn't work too well. Where can I get the stuff professional people use to put over their baskets?
