Screen your view of the outdoors with an indoor forest of skinny Christmas trees. Anchor the trees in wet sand in galvanized buckets, and add watering cans for a garden theme.
Accent windows with swags of artificial eucalyptus and silk or dried red flowers. To make each swag, bundle stems of eucalyptus, red twigs, dyed-red baby's breath, and bear grass into a small swag; assemble red yarrow into a smaller bouquet and wire it over the swag's stem ends. Tie a bow over the joint and bend one eucalyptus branch to form a hanger to hook over the curtain rod.
Frame a window from inside with miniature lights. Run a strand of lights along the sill and top of the sash, securing it with small pieces of masking tape. Suspend a lighted tree-topper ornament from the sash (or pop a specialty add-on ornament onto one of the miniature lights). Hide the wires with greenery.
