Integrate Lower Horizontal Shelf

What happens here

After allowing the initial stone veneer layers to set slightly, create a precisely measured horizontal opening in the stone veneer to accommodate the lower wooden shelf. This shelf, assumed to be made from reclaimed wood, should be pre-finished and cut to the exact dimensions required. Apply adhesive or mortar to the back of the shelf's mounting area and carefully slide the wooden shelf into the opening. Ensure it is perfectly level and flush with the surrounding stone veneer. Temporary supports may be necessary to hold the shelf in place while the adhesive cures. The video shows this shelf having a rich, dark wood finish.

Goal: Once several rows of stone veneer are in place, a long horizontal shelf, crafted from wood, is carefully inserted and secured into a pre-planned opening within the veneer layer. This shelf serves as a mantle or base for the TV and lower display items.
