# Onion Skinning: Displaying Drawings from Next and Previous Panels

With onion skinning in Toon Boom Storyboard, you can display the drawings from previous panels in the current panel so you can see where to place the drawings for the next panel. You can also display drawings from next panels in the current panel so you can see where to place the drawings for the previous panel. You can use these drawings as a reference to determine the size, angle or position of the drawing in the current panel.

You can display the drawings of up to three previous panels or next panels in the onion skin.

Use the Onion Skin button in the Onion Skin toolbar to turn the onion skin feature on and off.

In the Drawing View, Toon Boom Storyboard displays the drawings of the previous and next panels in the onion skin in a different colour so that you can distinguish them. You can also use the onion skin in the Timeline View to display drawings in the previous and next frames in the current frame. Toon Boom Storyboard also makes use of a flipbook feature allowing you to rapidly move between drawings.

- Select one of the following options from the Show Previous button in the Onion Skin toolbar:

- No Previous Panels : displays only the drawings in the currently selected panel.

- Previous Two Panels : displays the drawings of the previous two panels before the drawings in the current panel.
