Then I pack up my car with gardening gloves and shears, NO money, that's the best part! and go a-searching. It is amazing what you can find alongside your local country roads.
I get out when I see something intriguing growing in the ditches or side of the road and clip off a few sprigs of each. Watch out, some of them have vicious thorns, my finger tip is pulsing as I type! And count on everyone who passes you by to stare in confusion!
When I have enough I pack it up and bring my "gatherings" home to start putting the branches, grasses, flowers and berries into the galvanized tin vase. The great thing about roadside harvesting is that no water is needed as they dry to a nice patina without it.
Then I fill a wire basket with nuts...(don't let the squirrels see!)
