4" cypress trees are available in the greenhouse department at Home Depot for a little under $5.00 each. They come in a small plastic planter that should go directly in the recycling bin!
Burlap is inexpensive and can be purchased at most fabric stores. A 7"x14" strip of burlap is folded in half, sewn along each side and turned inside out to create a small rustic bag. I took the trees out of the red plastic container - left the plastic pot that remained - slipped a plastic bag around that (to prevent leaking when watered) and dropped it into my burlap bag.
Fold edges of burlap bag in and tuck green moss into the to the top to give this a more finished look.
