Flower arranging in November

I know it's getting late for flowers around here but there still are berries. I offered to do some large church arrangements for a memorial service this weekend and I'm only a little worried that I won't find enough pretty stuff.  Last week I used mostly winterberry fruit which is excellent this year.  I augmented that with some Rosa multiflora hips, some Japanese barberries and leaves of Forsythia and burning bush.  My wife thought it was very successful- I hope she wasn't just being nice!!!
