I had already preserved this piece of driftwood following these steps. If your driftwood fits into the oven you can bake it on low heat (200 degrees) for about an hour. This will get the bugs out, and dry the wood out to prevent rot later on. I typically bake pinecones at Christmas time.
This piece also already had holes drilled in it. But you can easily drill holes into the wood.
I picked up these fake succulent pieces at Michael's when they were on sale for $1 a piece.
Then I simply cut the stems to fit and glued them into the holes.
There you have it. Super easy, but packs a punch!
