They way that you prepare an indicator using and onion and beetroot depends on what type of indicator you want to prepare (i.e.: Litmus, pH, redox or other). Generally, you will cut pieces off of the onion and beetroot and put them each in separate flasks adding ethanol or other liquid you want to use for your indicator project.

To prepare an indicator using onion and beetroot, you can grind or blend each separately with water to extract their pigments. The red pigment from beetroot will be acidic (pH < 7) and turn yellow in basic solutions (pH > 7), while the pigment from onion will be yellow in acidic solutions and red in basic solutions. These can be used to test the acidity or alkalinity of a solution by observing the color change.
