Pinecone Topiary Trees- take apart pinecones...then hot glue onto brown spray-painted tree-shaped cones. They look so natural...like they grew that way! Make several sizes and group them with natural greenery, burlap ribbon...& other naturals - nuts, dried berries, etc.
Here is a simpler garland. You can add your wedding colors in the flowers, still do a lace topper w/grey, coral or champagne (?) linen under, tall centerpieces, white chairs, chandeliers overhead - very elegant
