Quake hold or museum tack works great, it is reusable, and clear. It comes in thin sheets, about 3x5 two per pack, you roll a small bit between your fingers and stick it down. A little goes a long way. When you are ready to move the item, just peel it off and it leaves no residue, roll it between your fingers and it is good for the next stick. We use it under all of our things in the event of an earthquake, and since I live in San Francisco, that is a fairly common event. It holds heavy vases, my sailing ship models, and my clocks. If you can't find it, pm me, and I will send it to you.
