Triplets! If you need a substantial flower arrangement for a big table, do it in triplicate. This is also the perfect time of the year to pick the last of the hydrangeas. Don't worry if they're a little faded; it just adds to the autumnal look. If you wrap the stems in a wet paper towel, then put it in a plastic bag, they will dry slowly and last forever.
The beauty of fresh with the longevity of silk...the perfect flower arrangement for Staging! Or just life in general.
And oh BTW, I got the vases at Goodwill for a song.
