Spontaneously make a tray
When you are stuck and quickly need a tray to hold some of your items, use cardboard and aluminum foil to design your own platter. Cut a piece of cardboard to your desired shape and size and cover it with a heavy duty foil.
You can also use aluminum foil alone if a cardboard is out of reach. This can hold items like nails and screws in our workshop or work area in case you forgot your tray, do not own one or cannot quickly reach yours.
