Here is what I found works best in my kiln. First use a piece of thin clear on the bottom, following the template provided. Place a round pebble on the bottom point. Place a 3mm piece of clear on top. Prior to that add rectangular piece on top. The top layer of 3mm glass will cover whatever piece is placed on top and assume that it is fused together. If you use a top rectangular piece of thin dichroic, then cap it with a piece of thin clear. If you use a 3mm rectangular piece on top then it does not need to be separately capped. If you want to decorate the post of the swizzle stick, do so before capping it with clear. Finally use the firing schedule that is provided by Glass hoppa, but add 15 degrees to all the "processing temperatures" because he is firing per spectrum glass. Use thin fire paper to fire them all.
The glasshoppa current projects are only accessible through Patreon. His projects are certain worth it.
